The CW’s 90210 is not above a stunt casting. In the show’s first season, old school stars Shannen Doherty, Tori Spelling, and Jennie Garth (who was, until recently, a recurring character) all saw major screentime, and Rumer Willis had a nice bit role earlier this season. But the show’s latest move doesn’t make all that much sense: Ryan O’Neal is going to play Teddy Montgomery’s movie star dad?

The one-time Hollywood bad boy was spotted filming scenes in a vintage corvette with Trevor Donovan this week. It’s unlikely that most regular 90210 viewers know much about O’Neal – beyond, of course, his longtime relationship with the late Farrah Fawcett – so his sudden appearance on the show seems a little out of nowhere.
