1) Total number of films you own on DVD/video: Um... if we're just counting films as opposed to TV stuff, probably somewhere around 80 or so. Adding in TV stuff boosts that total significantly (Babylon 5, Black Books, and rotwang's Buffy/Angel stuff, for instance).
2) The last film I bought: I haven't bought any for myself in a while, but I was bought The Incredibles on DVD for my recent birthday.
3) The last film I watched: Hitchhiker's Guide To The Galaxy at the cinema on Saturday night (and I enjoyed it quite a lot)
4) Five films that I watch a lot or that mean a lot to me:
The Breakfast Club
Star Wars (Episode IV, of course)
Shaun Of The Dead
5) Five people to tag to do this next:
jphekman (if she ever reads this ;))
