Man says show, movie infringe on his name
A Hot Springs, Mont., man who legally changed his name to Jack Ass in 1997 has filed a lawsuit against Viacom International Inc., the parent company of MTV, producer of the Jackass television show and movie. In his complaint, the plaintiff alleges that he changed his name to Jack Ass and created a character named Andi Ass to raise awareness about the dangers of drinking and driving after his brother Andy was killed in a vehicle accident. He accuses MTV of copyright infringement.
