Former Revlon model and one-time unoffical Hollywood ambassador to China, Deborah Raffin first hit her stride in the made-for-TV movie, Once Is Not Enough (1975). I fell in love with her when she played the beautiful Chris Farris in the made-for-TV mini-series, The Last Convertible (1979), still one of my favorite television films of all-time.
Raffin was next in line for the role of Sandy in Grease after Susan Dey turned it down, As fate would have it, producer Allan Carr bumped into Olivia Newton-John at a dinner party and...well, you know the rest.
Raffin was seen on 7th Heaven for a couple years and most recently on The Secret Life of the American Teenager. Not sure what she's up to these days and can't find any up-to-date information.
Here's Deborah in a scene from Once Is Not Enough.
