Got into an argument during a dinner with Hamish McAlpine, the British
distributor of his upcoming movie Ken Park (2002), over politics. Clark punched
him, which prompted McAlpine to pull the movie from the London
Festival.
An autographed poster of his film Wassup Rockers hangs in Circle Theater, a small theater in Tulsa, Oklahoma (his hometown) that plays independent films and, occasionally, films by University Of Tulsa students.
