(From imdb): Scarlett Johansson pulled out of appearing in the second Mission: Impossible sequel after Tom Cruise tried to convert her to scientology, according to reports. Cruise, who produces the action adventures, met with Johansson ahead of casting for the upcoming Mission: Impossible 3 and took her to one of the controversial religion's headquarters, claims Radarmagazine.Com. A source tells the website, "After two hours of proselytizing, Cruise opened a door to reveal a second room full of upper-level Scientologists who had been waiting to dine with the pair, at which point the cool-headed ingénue politely excused herself." Officially Johansson quit the film because of scheduling conflicts after the film was delayed so Cruise could make War Of The Worlds.
