Well Cinematical is officially in Park City, Utah for the 2009 Sundance Film Festival, and to kick-start our coverage we have this exclusive clip from The Informers, which is one of (if not the) largest premiere here this year. Based on the book by Bret Easton Ellis, The Informers follows a week in the life of several seedy individuals -- movie executives, rock stars, a vampire, a kidnapper -- as they mix and mingle in 1983 Los Angeles. With an all star cast including Billy Bob Thornton, Kim Basinger, Mickey Rourke, Winona Ryder, Brad Renfro, Amber Heard and more -- The Informers, directed by Gregor Jordan, looks to spread its dirty, erotic stench all over Park City this week. Check out the clip below, which features Mickey Rourke and the late Brad Renfro (in his final role).
