There was supposed to be a remake of Harvey - made for television - with Harry Anderson in the Stewart role. It never made it to TV. And don't forget the actress who played Elwood's sister (Josephine Hull?) That was her role alone.

There was a short-lived TV series based on Casablanca. I forget who was in it. Aside from the lead actors, who could replace Peter Lorre and Sydney Greenstreet? They were two of the best back-up actors ever.
