Does it ruin the illusion of a character if the voice actor is revealed? When they announced that Rhianna did the voice of Trip, all I could see and hear was Rhianna instead of the afro-headed girl with an alien as a friend. I watched the movie though. Since it was a kid's movie, of course, I wasn't really impressed. But I like to watch all the new movies to see if one can surprise me and make me applaud its craftsmen ship.
