I couldn't not post a christmas trailer, so here you have one for A Christmas Carol. It's based on the novel by Charles Dickens, and is the tale about the old Ebenezer Scrooge and Tiny Tim... you know the story!
This trailer is called A Fireside Chat with Lionel Barrymore. (Barrymore was actually going to play Scrooge, but because of illness he couldn't. So instead he suggested his friend Reginald Owen, who ended up playing the part.) In the trailer Barrymore sits by the fireside (doh!), and introduces the novel and film. Gotta love these kind of trailers!
See it here, at 8,49Mb. Merry christmas!
