Trailerology: Serenity and The Memory of a Killer

I should just start mirroring Twitch, or at least their trailer links. First up is a link for all you Buffy fans: a trailer for Joss Whedon's Serenity. Second, what looks to be a great thriller from Belgium, The Memory of a Killer. It was their Oscar submission for Best Foreign Film, and had a better title back then: The Alzheimer Case.
