Hasselhoff's 'Knight Rider' Set Back

David Hasselhoff's dreams of taking his Knight Rider TV show to the big screen have hit a snag, after a dispute with his movie studio. The Baywatch hunk has spent years trying to resurrect the hit series about a talking car and had reportedly lined up a studio to make the movie - with Ben Affleck being touted to play Hasselhoff's Michael Knight character. But the 51-year-old has parted ways with the studios after an "artistic difference". A source tells American news site The Scoop, "The studio didn't want the car to talk. David was like, 'Hello?' So he's switching studios."

Speechless K.I.T.T. aside, think of it: Ben Affleck as everyone's favorite pseudo-cool bubblehead. Perfect casting.
