Nicolas Cage

While it's his co-star's character, Riley, who owed $6 million in taxes in "National Treasure: Book of Secrets," Cage has dealt with his own tax issues in real life. The IRS accused the actor with falsely writing off $3.3 million in personal charges to his company, Saturn Productions, in February 2008. He settled the case in September, agreeing to pay $666,465 in taxes and penalties.
