Former ROSEANNE star John Goodman is being sued by the bosses of a German film company after allegedly backing out of a movie, in which he was to play the Pope. Goodman reportedly entered into "an oral agreement" to take on the religious role of POPE SERGIUS in Constantin Film Produktion's upcoming project POPE JOAN, according to legal papers filed in Los Angeles. Constantin executives claim the actor has now reneged on the deal, threatening the entire project. In the lawsuit, obtained by TMZ.com, Constantin producers allege Goodman "knew that Constantin would rely on his promise by not casting or seeking to cast any other actors for the role of Pope Sergius." As a result, the movie studio heads state they have lost "significant sums" on pre-production. The studio is asking for more than $3 million (GBP1.5 million) to cover their losses.
