Live-action funfest The Zookeeper from MGM Films has added more star power to its already formidable stable at hand, Dark Horizons reports.

Adam Sandler, Cher, Jon Favreau, Sylvester Stallone and Judd Apatow will provide voices for the animals in the comedy.

The film revolves around zoo animals trying to teach the keeper their methods of dating and mating to help him win back the woman of his dreams.

Sandler, Cher, Favreau, Stallone and Apatow (who will voice a capuchin monkey, a giraffe, a bear, a lion and an elephant respectively) will join a stellar cast that already includes Kevin James, Rosario Dawson, Jim Breuer, Faizon Love and Bas Rutten.

Frank Coraci (Click, The Wedding Singer) is directing from a screenplay by Jay Scherick, David Ronn, Kevin James, Rock Reuben and Nick Bakay. Shooting is set to start later this summer.
