Russell Brand lends his voice to E.B., the son of the Easter Bunny. Unfortunately for his dad, E.B. doesn't want to be the new Easter Bunny. He wants to play the drums in a band. When it comes time to hand down the title, the young bunny runs away to Hollywood. He winds up meeting Fred, a (human) son that also wants more than what his father has planned. The two dodge an elite force of ninja bunnies as they try to find their place in the world.
To be honest, I really like Russell Brand. I was very surprised to hear that he was going to be in a family-friendly film. (Maybe Katy really has mellowed him.) Amazingly, I even liked him toned down. James Marsden, though, takes a little bit of getting used to. It's OK for a cartoon rabbit to mug for the camera. It's not so cute when it's a grown man. I didn't let him get in the way of enjoying the movie though.
I suppose this is a movie that completely depends on your mindset going in. If you are going to to see a funny animated movie, you'll probably like it. If you're going in looking for the best of everything, you won't find that here. It's just a cute feel-good movie.
