Tom Cruise is facing a $1 billion copyright infringement lawsuit over the Mission Impossible: Ghost Protocol screenplay. In court documents filed in California in December (13), screenwriter Timothy Patrick McLanahan claims he came up with the basis for the film in 1998. In the legal papers, obtained by RadarOnline.com, McLanahan alleges he copyrighted a screenplay, titled Head On, and shopped it to agents at William Morris Agency, but they passed on it. He alleges WMA executives sent it to another firm, Creative Artist Agency, where Cruise and his agent, Rick Nicita, picked up the idea for the 2011 film. Nicita is married to Cruise's former producing partner Paula Wagner. The court documents read, "I immediately recognized that the scripts for this movie had been illegally written and produced from Head On's 1998 copyright." McLanahan is now seeking monetary damages from the actor and executives at Paramount Pictures and several production companies.
