Big Bang Theory Star Kaley Cuoco Joins I, Hop

Kaley Cuoco (who plays the character Penny in The Big Bang Theory) has signed on to star alongside Russell Brand in the Easter Bunny comedy I, Hop. Described as "the world's worst houseguest," Brand plays an Easter Bunny who is accidentally injured by an unemployed slacker played by James Marsden, who is then forced to take the holiday creature in until he recovers. As one might expect, wacky hijinks ensue, and both characters eventually "learn what it takes to finally grow up." Yawn.

According to THR, Cuoco will play Marsden's character'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." The film is planned as a live-action / CGI blend (ie Brand's Easter Bunny will be CGI while the rest of the film is live action). Tim Hill (Alvin and the Chipmunks) is directing. The script is by Cinco Paul, Ken Daurio and Brian Lynch.

The film is the first live-action production from Universal Pictures' Illumination Entertainment, the guys behind the computer animated feature Despicable Me. That film looks promising, this just seems like a high concept cash grab – The Santa Clause meets Step Brothers, or what not.
