X-Men: First Class, like X-Men Origins: Wolverine, is a prequel to the X-Men films.
Judd Apatow created fake films for the new movie, Funny People.
A third film is secretly bringing back one of Apatow’s favorite leading ladies, the beautiful breakout from “The 40-Year-Old-Virgin,” who will also be playing herself. “[Sandler’s George Simmons character] made a romantic comedy called ‘Mistake’ with Elizabeth Banks,” he explained. “There’s all sorts of posters, some we shot scenes for.”
The one I’m most eager to see might be Sandler’s “Splash” take-off. “There’s a movie called ‘Mer-man,’ that he’s in as well,” Apatow said with a grin on his face. “I’ve heard they already sold ['Mer-man'] to be a real movie after we made it as a joke.”
