Everyone knows that Joan Crawford's best movie was Sudden Fear (who can resist a love story between Joan Crawford and Jack Palance - of course, the "love story" is just the first 1/3 of the film, until Joan discovers that her new husband has a girlfriend, then you get classic Joan... but I digress). But I have to say that my Favorite "Joan Crawford moment" is in Strait Jacket. Both films are fun, the types best seen with a group of friends, but Strait Jacket has so many over-the-top howling out loud moments that it's pretty irrestible. Directed by: William Castle (1964), and screenplay by Robert Bloch, apparently it has recently come out on DVD.
