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 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 U.S. Government following 9/11.

He says, ""The paranoid conspiracy freak inside me is starting to think this has something to do with the film.""
