"Big Bang" star lands lead in "I Hop" film

LOS ANGELES – Kaley Cuoco, one of the stars of CBS' sitcom "The Big Bang Theory," has booked her first studio feature role with "I Hop," a live-action/computer-animated hybrid comedy.

James Marsden stars as an out-of-work slacker who accidentally injures the son of the Easter Bunny (voiced by Russell Brand) and must take him in as he recovers.

Cuoco will play Marsden's sister, who allows Marsden to live with her when he gets kicked out by his parents, and finds herself dealing with the injured heir to the Easter Bunny throne.

Tim Hill ("Alvin and the Chipmunks") is directing the Illumination Entertainment/Universal project.

Cuoco has spent the better part of the decade cultivating a successful TV career with "Big Bang" and such shows as "Charmed" and "8 Simple Rules." She has appeared in several indie movies, but this is her first move capitalizing on the success of the CBS hit.
