When Spike Lee was asked following the screening of his movie Red Hook Summer at the Sundance Film Festival what he would have done differently if he had access to a big Hollywood budget, he launched into a high-decibel, expletive-laced rant at studio executives that left those in his audience somewhat shell-shocked. The question was put to him during a Q&A by Chris Rock -- and Lee seemed to indicate that the actor/comedian had asked him the same question in private earlier. "We never went to the studios with this film, Chris," Lee retorted. "I told you, I TOLD you ... I bought a camera and said we're gonna do this motherf***ing film ourselves!" That had always been his plan, he insisted, because "I didn't want to hear no motherf***ing notes from the studio telling me ... about what a young 13-year-old boy and girl would do in Red Hook," the downscale Brooklyn neighborhood where the movie was filmed. Studio executives, Lee railed, "know nothing about black people -- nothing!" Critics attending the screening gave the film a mostly negative reception on Twitter as soon as it was over, a person from ComingSoon.net describing it "as one of the worst movies to ever premiere at #sundance," although a handful found much about it to admire. It was, said, the Los Angeles Times 's Steven Zeitchik on Twitter, Lee's "most interesting/ambitious film" in years. Tweeted Adam B. Vary of Entertainment Weekly "Bizarre, flawed, passionate, and that's just Spike Lee's rant-y post-screening Q&A, featuring a Chris Rock cameo!"
