Bob's Picks: Several Premieres?

Tonight is a night of "Bob's Picks" on TCM, when Robert Osborne picks four movies more or less the way a Guest Programmer would, except of course Robert doesn't sit down with himself to present them. The films Robert Osborne has selected are:

8:00 PM Frenchman's Creek, a pirate movie with Joan Fontaine;
10:00 PM My Cousin Rachel, based on a story by Daphne Du Maurier;
Midnight Who Done It?, with Abbott and Costello becoming detectives; and
1:30 AM The Ritz in which Jack Weston, trying to escape from his gangster brother-in-law, accidentally winds up in... a gay bathhouse!

I have a feeling the last three movies may be TCM premieres. Normally, when you look at the printable monthly schedule, there's a nice one-sentence synopsis of the movie. For Frenchman's Creek, for example, that's "A British noblewoman flees the life of the court to run off with a French pirate." But for the last three films, there's no synopsis. That's a sign that the movies haven't been on TCM before.

The folks on the TCM boards claim that the last time Frenchman's Creek aired (I didn't see it), TCM had a very bright print, so be warned.
