Watching the rest of a movie I started last night called "Friday the 13th," an early British talkie with Jessie Matthews and Ralph Richardson, Edmund Gwenn and a whole slew of people. Emlyn Williams wrote the script and plays a blackmailer in it. He's really good, but then again, so is everyone else in the cast.
It starts with a bus wreck and then takes you back to tell you the stories of the various people on the bus.
