Question: When the Wachowskis presented their script for Assasins, what production studio were they at?
About the article "The Matrix", section "Development".

Candidate passages:
During "The Matrix Reloaded", "The Matrix Revolutions", "Animatrix" and "Enter the Matrix" production, the Wachowskis created EON Entertainment (not to be confused with Eon Productions), their production company to coordinate and direct all involved partners.
It is also where the films were edited together, after the various FX vendors sent their finished work.
EON's internal VFX team, ESC, did a number of visual effect shots for the two Matrix sequels and coordinated the other vendors.
ESC was shut down in summer 2004.
Anarchos Productions (credited in "Cloud Atlas" as Anarchos Pictures) is their production company that has been billed for all their films starting with "V for Vendetta", but EON is still being mentioned at the production credits of their latest film, "Cloud Atlas".
"Kinowerks" is their postproduction and effects studio, based in Ravenswood, Chicago.
It has been acclaimed for its green-friendly design.
Roger Ebert was invited to watch a restored print of "The Godfather" in the "Kinowerks" facilities and met the Wachowskis, but he was oblivious to the fact the studio belonged to them.
The "Chicago Tribune"'s Christopher Pirelli has interviewed the Wachowskis in the facility but was instructed to keep its exact location a secret, as the filmmakers want to avoid having fans showing up on the front door.
Prior to working in the film industry, the Wachowskis wrote comic books for Marvel Comics' Razorline imprint, namely "Ectokid" (created by horror novelist Clive Barker) in 1993 as well as writing for Epic Comics' "Clive Barker's Hellraiser" and "Clive Barker's Nightbreed" comic series.
In 2003, they created Burlyman Entertainment and have released comic books based on "The Matrix" as well as two original bi-monthly series:  "Shaolin Cowboy" – created, written, and art by Geof Darrow (the Wachowskis contributed the opening dialogue to each issue)  "Doc Frankenstein" – created by Geof Darrow and Steve Skroce, written by the Wachowskis, with art by Skroce.  
"Ninja Assassin" was directed by James McTeigue, and produced by Joel Silver and the Wachowskis.
The project was inspired by the ninja scenes featured in the Wachowskis' 2008 film "Speed Racer", in which the actor Rain had impressed the Wachowskis with his portrayal as a fighter.
The Wachowskis were dissatisfied with the original script, and hired J. Michael Straczynski to write a new draft for the film six weeks before it began production.
Medienboard Berlin-Brandenburg provided filmmakers US$1 million in funding, and Germany's Federal Film Fund provided an additional US$9 million to the film's funding. 
In 1994, the Wachowskis presented the script for the film "Assassins" to Warner Brothers.
After Lorenzo di Bonaventura, the president of production of the company at the time, read the script, he decided to buy rights to it and included two more pictures, "Bound" and "The Matrix", in the contract.
The first movie the Wachowskis directed, "Bound", then became a critical success.
Using this momentum, the brothers later asked to direct "The Matrix".
Producer Joel Silver soon joined the project.
Although the project had key supporters like Silver and Di Bonaventura to influence the company, "The Matrix" was still a huge investment for Warner Bros, which had to invest $60 million to create a movie with deep philosophical ideas and difficult special effects.
The Wachowskis therefore hired underground comic book artists Geof Darrow and Steve Skroce to draw a 600-page, shot-by-shot storyboard for the entire film.
The storyboard eventually earned the studio's approval, and it was decided to film in Australia to make the most of the budget.
Soon, "The Matrix" became a co-production of Warner Bros. and the Australian company Village Roadshow Pictures.
Some German journalists called "Cloud Atlas" "the first attempt at a German blockbuster" (although the 1984 fantasy "The NeverEnding Story" was written about in similar terms before its release).
Tykwer and the Wachowskis filmed parallel to each other using separate camera crews.
The Wachowskis directed the 19th-century story and the two set in the future, while Tykwer directed the stories set in the 1930s, the 1970s, and 2012.
Warner Bros. Pictures representatives argued they were happy with the film's 164-minute running time, after previously stating that it should not exceed 150 minutes.
Filming began at Studio Babelsberg in Potsdam-Babelsberg, Germany, on 2011, which was the base camp for the production during its shoot.
Other locations include Düsseldorf, in and near Edinburgh and Glasgow, Scotland, and the Mediterranean island of Majorca, Spain.
Glasgow doubled for both San Francisco and London.
Scenes filmed in Scotland also feature the recently built Clackmannanshire Bridge near Alloa.
The "Big Island" and "Pacific Islands" stories were actually shot on Majorca, mostly in the World Heritage site of the Serra de Tramuntana mountains.
Scenes were shot at Cala Tuent and near Formentor, amongst others.
The opening scene of the film, when Adam Ewing meets Dr. Henry Goose, was filmed at Sa Calobra.
Port de Sóller provided the setting for the scene when the 19th-century ship is mooring. 
  Keanu Reeves as Thomas A. Anderson / Neo: A computer programmer in Metacortex corporation who moonlights as a hacker.
Reeves described his character as someone who felt that something was wrong, and was searching for Morpheus and the truth to break free.
Will Smith turned down the role of Neo to make "Wild Wild West", because of skepticism over the film's ambitious bullet time special effects.
He later stated he was "not mature enough as an actor" at that time, and that if given the role, he "would have messed it up".
Nicolas Cage also turned down the part because of "family obligations".
Warner Bros. sought Brad Pitt or Val Kilmer for the role.
When both declined, the studio pushed for Reeves, who won the role over Johnny Depp, the Wachowskis' first choice.
Laurence Fishburne as Morpheus: A human freed from the Matrix, captain of the "Nebuchadnezzar".
Fishburne stated that once he read the script, he did not understand why other people found it confusing.
However, he had a doubt if the movie would ever be made, because it was "so smart".
The Wachowskis instructed Fishburne to base his performance on the character Morpheus in Neil Gaiman's "Sandman" comics.
Gary Oldman and Samuel L. Jackson were also considered for the part.
Despite widespread rumors, Sean Connery was offered the role of the Architect in the sequels, not that of Morpheus.
Carrie-Anne Moss as Trinity: Freed by Morpheus, crewmember of the "Nebuchadnezzar", Neo's romantic interest.
After reading the script, Moss stated that at first, she did not believe she had to do the extreme acrobatic actions as described in the script.
She also doubted how the Wachowskis would get to direct a movie with a budget so large, but after spending an hour with them going through the storyboard, she understood why some people would trust them.
Moss mentioned that she underwent a three-hour physical test during casting, so she knew what to expect subsequently.
The role made Moss, who later said that "I had no career before.
None."
Janet Jackson was initially approached for the role but scheduling conflicts prevented her from accepting it.
In an interview, she stated that turning down the role was difficult for her, so she later referenced "The Matrix" in the 'Intro' and 'Outro' interludes on her tenth studio album "Discipline".
Hugo Weaving as Agent Smith: A sentient "Agent" program of the Matrix whose purpose is to destroy Zion and stop humans from getting out of the Matrix.
Unlike other agents, he has ambitions to free himself from his duties.
Weaving stated that the character was enjoyable to play because it amused him.
He developed a neutral accent but with more specific character for the role.
He wanted Smith to sound neither robotic nor human, and also said that Larry and Andy Wachowski's deep voices had influenced his voice in the film.
When filming began, Weaving mentioned that he was excited to be a part of something that would extend him.
Jean Reno was offered the role, but declined, unwilling to move to Australia for the production.
Joe Pantoliano as Cypher: Another human freed by Morpheus, but one who regrets taking the red pill and seeks to be returned to the Matrix.
Pantoliano had worked with the Wachowskis prior to appearing in "The Matrix", starring in their 1996 film "Bound".
Julian Arahanga as Apoc: A freed human and crew member on the "Nebuchadnezzar".
Anthony Ray Parker as Dozer: A "natural" human born outside of the Matrix, and pilot of the "Nebuchadnezzar".
Marcus Chong as Tank: The "operator" of the "Nebuchadnezzar", he is Dozer's brother, and like him was born outside the Matrix.
Matt Doran as Mouse: A freed human and programmer on the "Nebuchadnezzar".
Gloria Foster as the Oracle: A prophet who still resides in the Matrix, helping the freed humans with her foresight and wisdom.
Belinda McClory as Switch: A human freed by Morpheus, and crew member of the "Nebuchadnezzar".
Paul Goddard as Agent Brown: One of two sentient "Agent" programs in the Matrix who work with Agent Smith to destroy Zion and stop humans escaping the system.
Robert Taylor as Agent Jones: Second sentient "Agent" program working with Agent Smith.
Ada Nicodemou as DuJour (The White Rabbit Girl), a reference to the White Rabbit in "Alice's Adventures in Wonderland".
