Peg, you mean Bert Lahr was hired to play the Tin Man and then later recast as the lion?

Jerry, I never did "buy" Olivia Newton-John as a high-school student in "Grease." I found out later that she was 31 when the movie was made.

Seems to me that many movies made in the 1930s and 1940s had actors/actresses in their mid-twenties or older cast as 18-year olds. When I look back at my high school and college yearbooks and see how young we all looked, and then I look at who Hollywood thinks is believable playing the same, it's laughable!

JJ, I know MGM wanted Shirley Temple. We should all be grateful that folks don't always get what they ask for!

The TV shows that are based on popular films are often prime examples of bad casting. "Mash" comes to my mind first. Alan Alda's "Hawkeye" was just not the same character as Donald Sutherland's -- and not nearly as irreverent.
