More details have emerged, and thankfully we won't be subjected to any Sandler-on-Sandler twin-cest in Jack and Jill; the premise is that Jack's wacky twin Jill comes for Thanksgiving and just won't leave. Hijinks ensue, etc. Katie Holmes in in talks to play Jack's wife, who is caught in the middle of this sibling snafu, according to The Hollywood Reporter. Al Pacino will also be in Jack and Jill as himself. Obviously.
Sandler is still a sure thing when it comes to big studio comedies, no matter how inane, but it will be interesting to see how Holmes fits into the picture. She also has several projects coming up, both finished and in the works, that span genres, from horror (Don't Be Afraid of the Dark) to indie dramas (The Extra Man, The Romantics). Hopefully, at least one of these roles will convince us she's more than the starry-eyed wife of Tom Cruise. Somehow, I doubt Jack and Jill will be it, though.
