Yes, Jenny McCarthy is, technically, an actress. You'd be forgiven for thinking otherwise, since her filmography isn't exactly prolific. Though she earns humble props for attempting goofy, slapstick comedy, the former Playboy Playmate of the Year turned movie performer always gives off the impression that she's trying too hard to be funny. It's almost as if she's hell-bent on pulling attention away from her beautiful looks by acting so obnoxiously and boisterously. Mission failed.
