Shia LaBeouf claims filming "Transformers" felt like having a "a finger up your ass" -- and now, the actor says he's quitting big budget movies for good.
26-year-old Shia spoke with The Hollywood Reporter recently, swearing off studio flicks for the rest of his life ... in favor of a career in indie films -- saying, "I'm done ... There's no room for being a visionary in the studio system. It literally cannot exist."
Shia said, "You give Terrence Malick a movie like 'Transformers', and he's f**ked. There's no way for him to exist in that world."
Shia then gushed about the people behind his new movie "Lawless" -- saying, "These dudes are a miracle ... They give you the money, and they trust you -- [unlike the studios, which] give you the money, then get on a plane and come to the set and stick a finger up your ass and chase you around for five months."
