Braddon Mendelson is a producer, director and writer who was named as a defendant in the Rosa Parks v. LaFace Records lawsuit, but was subsequently dismissed from the case by the presiding judge.
 As a music video producer, Mendelson worked with some of the top R&B and Rap artists of the late 1990s, including Xzibit, Outkast, Bizzy Bone, Mo Thugs and Ice Cube.
 In 1997 he produced the feature film "Boogie Boy".
 The film was directed by Craig Hamann and Executive Produced by Academy Award winner Roger Avary, who were both collaborators on Quentin Tarantino's first film "My Best Friend's Birthday."
Emerging Producers is an educational and promotional workshop, organised since 2012 by Ji.hlava International Documentary Film Festival as part of its Industry Programme.
 The project is focused on the support of talented European documentary film producers by helping them with orientation in the film market, creating the space for coproduction, and arranging the contact with leading film professionals.
 It is the only programme of its kind designed for documentary film producers in Europe.
Glitterati is a 2004 film directed by Roger Avary assembled from the 70 hours of video footage shot for the European sequence of "The Rules of Attraction" in October 2001.
 It serves to expand upon the very minimally detailed and rapidly recapped story told by the character of Victor Ward (portrayed by Kip Pardue, featured in Avary's other film "The Rules of Attraction") upon his return to the United States after having traveled extensively around Europe.
 Expanding upon those events, the film was intended as a connecting bridge between "The Rules of Attraction" and a planned film adaptation of Bret Easton Ellis' 1998 novel "Glamorama", which was to be directed by Avary and star Pardue.
 Avary has called the film a "pencil sketch of what will ultimately be the oil painting of "Glamorama"."

 The cast includes Ray Winstone, Anthony Hopkins, Robin Wright Penn, Brendan Gleeson, John Malkovich, Crispin Glover, Alison Lohman, and Angelina Jolie.

 Pictures, and was available to view in IMAX 3D, RealD, Dolby 3D and standard 2D format.
