Another vote for "District 9". I truly think it is one of the best movies I have ever seen, seemlessly blending science fiction, political thriller and social commentary into one can't-take-my-eyes-away experience.
Also "Inglorious Basterds" - very well done, although I'm not quite sure why Tarantino made it. (It is NOT a history lesson!)
For a lock-yourself-inside-the-house marathon, "Band of Brothers", a 2001 HBO series based on Stephen Ambrose's book of the same title, about the paratroopers from the 101st Airborne Division starting with their training at Currahee, through the D-Day invasion, through the Battle of the Bulge, through the capturing of Hitler's Eagle's Nest. I've yet to see a series that is superior, although "I Claudius" comes close.
And "I Claudius" (BBC 12-part series from the mid '70's) - political intrigue, murder, mayhem, deviant sexual behavior of all stripes . . . tres delish!
