Not the best movie in the world, but what is truly amazing about it, are all the cameos from like a million world class actors like

*John Gielgud
*Evelyn Keyes
*Red Skelton
*Marlene Dietrich
*Frank Sinatra
*Peter Lorre
*Cesar Romero
*Buster Keaton
*Hermione Gingold
*John Mills
*Glynis Johns

and many, many more. It's incredible. I think it's the movie with the most famous actors ever produced. Worth seeing again and again, even if the movie itself could have been better
