Help remembering this movie?

I remember watching a movie when I was younger. There was something about a giant rabbit, maybe it was a person in a costume. It was not animated. This rabbit may have been dangerous, at least I thought it was. I remember a scene when the rabbit blew up someone's room, maybe with a rocket? I also remember a man yelling at the rabbit(looked like someone in a costume?) Lolz, sorry but that is all I remember.
