OK! Exclusive: Katie Lines Up Her Next Gig

OK! can exclusively reveal that, barring any last-second contract glitches, marathon mama Katie Holmes, whose first film since hooking up with Tom Cruise in 2005, Mad Money, will soon hit theaters, is making up for lost time by setting up her next on-screen role.

This time, Suri's mom will join fellow Scientologist celebs Giovanni Ribisi and Jason Lee in a film called The Other Side, a comedy-fantasy which is set to begin rolling in January in Los Angeles and the UK. Also along for the ride is co-star Rupert Friend (aka Keira Knightley's boy-toy) and possibly Woody Harrelson.

The quirky storyline has Katie playing a brilliant scientist attempting to solve a mystery of a remote island whose residents seem to have no connection with the outside world. Jam-band impresario Dave Matthews is composing the score and will add a cameo appearance to his growing list of acting credits, which includes a guest bit on House and a starring role in the family film Because of Winn-Dixie.
