Declan Patick McManus just doesn't have the same ring to it as Elvis Costello. Cary Grant doesn't seem quite as gallant with a name like Archibald Leach. And Lauren Bacall loses a bit of that haughty sassiness when you think of her as Betty Joan Perske.

Celebs and their agents know there's a lot to what's in a name, and while many stars were given monikers that made their parents proud, they're often not bright enough to light up a marquee.
