Question: When did the first films for the universe containing the Arrowverse start production?
Context: The Lockheed L-100 Hercules is the civilian variant of the prolific C-130 Hercules military transport aircraft made by the Lockheed Corporation.  Its first flight occurred in 1964.  Longer L-100-20 and L-100-30 versions were developed.  L-100 production ended in 1992 with 114 aircraft delivered.  An updated variant of the model, LM-100J, have completed its first flight in Marietta, Georgia on May 25, 2017, and is set to start production in 2018-2019. Earth Prime (or Earth-Prime) is a term sometimes used in works of speculative fiction, most notably in DC Comics, involving parallel universes or a multiverse, and refers either to the universe containing "our" Earth, or to a parallel world with a bare minimum of divergence points from Earth as we know it — often the absence or near-absence of metahumans, or with their existence confined to fictional narratives like comics.  The "Earth Prime" of a given fictional setting may or may not have an intrinsic value to or vital connection to the other Earths it exists alongside (although it appears to be the case that such Prime Earths — and sometimes the 'central universes' in which those Prime Earths exist as well — are portrayed in fiction to be vital to the existence of the other Earths). The "Babylon 5" television show and associated television movies created a fictional universe containing a large number of planets, moons, and other locations. The Arrowverse is a shared fictional universe that is centered on television series airing on The CW, developed by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, Phil Klemmer, and Geoff Johns, based on characters appearing in publications by DC Comics.  The shared universe, much like the DC Universe in comic books or the cinematic DC Extended Universe, was established by crossing over common plot elements, settings, cast, and characters.  The Arrowverse stars Stephen Amell as Oliver Queen / Green Arrow, Grant Gustin as Barry Allen / Flash, Megalyn Echikunwoke as Mari Jiwe McCabe / Vixen, with an ensemble cast leading "Legends of Tomorrow", including Arthur Darvill as Rip Hunter, Caity Lotz as Sara Lance / White Canary, Brandon Routh as Ray Palmer / Atom, Dominic Purcell as Mick Rory / Heat Wave, with Victor Garber and Franz Drameh as Martin Stein & Jefferson "Jax" Jackson / Firestorm.  Russell Tovey stars as Ray Terrill / The Ray. Gabriel Scognamillo (27 October 1906 – 31 May 1974) was an Italian art director.  One of the first films he worked on was Jean Renoir's provocative 1931 film "La Chienne".  Two years later he had moved to Hollywood where one of his first films there was MGM's production of "The Merry Widow" (1934) with Maurice Chevalier and Jeanette MacDonald. "N" = 4 supersymmetric Yang–Mills (SYM) theory is a mathematical and physical model created to study particles through a simple system, similar to string theory, with conformal symmetry.  It is a simplified toy theory based on Yang–Mills theory that does not describe the real world, but is useful because it can act as a proving ground for approaches for attacking problems in more complex theories.  It describes a universe containing boson fields and fermion fields which are related by 4 supersymmetries (this means that swapping boson, fermion and scalar fields in a certain way leaves the predictions of the theory invariant).  It is one of the simplest (because it has no free parameters except for the gauge group) and one of the few finite quantum field theories in 4 dimensions.  It can be thought of as the most symmetric field theory that does not involve gravity. Sunoco's Fulton ethanol plant in Fulton, New York is the first such facility owned by the company.  The plant is spread over an area of 115 acres in Riverview Business Park and includes a 250,000 ft² brewhouse.  The plant has the capacity to produce 85m gallons of ethanol annually.  Northeast Biofuels opened the plant in 2008; however, design flaws led to growth of bacteria in pipes that were difficult to clean.  Northeast Biofuels tried to rectify the problem and fix the pipes but failed.  The company filed for bankruptcy in 2009.  Sunoco bought the plant from Northeast Biofuels in June 2009 for $8.5m.  The company spent $25m, and contracted ICM, to repair the design flaws and start production.  The refurbished facility became fully operational with the production of the first batch of ethanol in June 2010. The Antonov An-70 is a four-engine medium-range transport aircraft, and the first large aircraft to be powered by propfan engines.  It was developed in the late 1980s by the Antonov Design Bureau to replace the obsolete An-12 military transport aircraft.  However, the dissolution of the Soviet Union prevented the mass production of the type.  The maiden flight of the first prototype took place on 16 December 1994 in Kiev, now independent Ukraine.  Within a year the prototype plane had suffered a mid-air collision.  A second airframe was produced and tests continued but numerous further attempts to start production have been unsuccessful. Santa Santita, or Magdalena, The Unholy Saint, is a 2004 Filipino film starring Angelica Panganiban and Jericho Rosales, directed by Laurice Guillen.  The film follows Malen, the daughter of an intercessor, her love affair with a hustler and gigolo, and her confrontation of the evil within her life.  Based on a script by Jerry Gracio, the film was picked up by Guillen in 2000 but did not start production because an appropriate actress for Malen could not be found.  After picking Panganiban, Guillen began work, and the eventual film was released on November 17, 2004, in the Philippines and March 11, 2005, internationally.  Receiving good reviews from "Variety" and the "Philippine Daily Inquirer", "Santa Santita" was one of only two films to be rated as Grade A by the Cinema Evaluation Board of the Philippines, and represented the Philippines at the Asiaticafilmediale festival in Italy and the Bangkok International Film Festival. The Justice League Universe (JLUDCEUUJLDCE), more commonly known by its unofficial name as the DC Extended Universe (DCEU), is an American media franchise and shared universe, centered on a series of superhero films distributed by Warner Bros.  Pictures, based on characters that appear in publications by DC Comics.  The shared universe, much like the original DC Universe in comic books, was established by crossing over common plot elements, settings, cast, and characters.  The films have been in production since 2011 and in that time Warner Bros. has distributed four films with more than ten in various stages of production.  The series has grossed over $3.1 billion at the global box office, currently making it the seventeenth highest-grossing film franchise.
