Jack Davenport has done a number of short movies. Unfortunately, those are difficult to get a hold of unless you're an avid festival-goer. Luckily some trailers are available; in those cases we've set a link. The shorts, ranging from experimental to fun to downright weird, are almost more interesting than the movies, so if you ever get a chance to see one of them, do it!
