From WENN:

Donnie Darko director Richard Kelly could be forced to miss the Cannes Film Festival because his passport is being reviewed by the US Government. Homeland Security is investigating 31-year-old Kelly, reportedly because there is a James Kelly on the terrorist watch list. Fearing he will be unable to attend the premiere of his new movie Southland Tales at Cannes later this month, Kelly has contacted a US senator and has recruited his mother to hunt out documents to help him prove his American citizenship. The Virginia-born writer/director fears the issue could be connected to the plot of his new movie, which is in part about security measures taken by the Us Government following 9/11. He says, "The paranoid conspiracy freak inside me is starting to think this has something to do with the film."
