What is Casting Couch? Despite the fact that the movie business seems to be slow to get back to work after the long weekend, it’s a column that’s managed to dig up a couple exciting casting coups. Bryan Singer out-scooped everybody in the news breaking business today when he suddenly started tweeting big updates on how the cast for his upcoming X-Men: First Class sequel, X-Men: Days of Future Past, was developing. He started off small by first confirming that a few members of the First Class crew would be returning. He tweeted, “I’d like to officially welcome back James McAvoy, Jennifer Lawrence, Michael Fassbender, & Nicholas Hoult to #XMEN for #DaysOfFuturePast.” But then he got a little crazy and started confirming rumors that actors from his original X-Men movies will be joining the film as well by tweeting, “Thrilled to announce @ianmckellen118 (Ian McKellan) & @SirPatStew (Patrick Stewart) are joining the cast of #XMEN #DaysOfFuturePast #magneto #professorX More to come…” Do you think we could get scenes where old Professor X and Magneto meet young Professor X and Magneto? The head spins with awesome possibilities.
