Katie Holmes gets the lead in The Romantics

Tom Cruise, 47, and Katie Holmes, 30, were spotted taking a walk in Boston, Massachusetts yesterday looking happy together as they shared a romantic walk. The couple is in Boston while Tom films a movie with Cameron Diaz. Holmes will be working again soon though.

Katie has just signed on to replace Liv Tyler as the female lead in the upcoming adaptation of Galt Niederhoffer novel “The Romantics.”

Ms. Holmes joins an already-stellar cast including Anna Paquin, Josh Duhamel, Malin Akerman, Elijah Wood, and Adam Brody. Holmes will also be an executive producer of the project. The movie is about eight friends who reunite for a wedding of two buddies as tension unfolds between the bride and maid of honor over the groom.

The movie starts filming this week in New York. Katie, 30, will play Laura, the maid of honor to Anna Paquin’s Lila, who’s the bride.

Laura and Lila are best friends who both have a past with the groom played by Transformers hunk Josh.
