No really, that is Catherine Zeta-Jones as the wife of Rick Moranis, an ersatz duke across the pond.

It's not as bad as you're probably thinking. Don't get me wrong -- it's as bad as any Fish Called Wanda/King Ralph wannabe/homage can get. But Idle still has some of his Monty Python instincts, and even if he does sing the songs for the film off-key, it honestly could have been a whole lot worse.

That's faint praise, yes, but it fits Splitting Heirs to a T.
