An action-film-with-comedy from the writers and director of Shaun of the Dead.
With (among many others) Simon Pegg, Edgar Wright, Bill Nighy, Martin Freeman of Hitchhiker's and the British The Office, Paul Freeman (dude, Belloq!) and Timothy Dalton.
And the score's by David Arnold.
This is already leonardpart6's favorite film and he hasn't even seen it yet.
P.S. Here's Moriarity's Ain't It Cool News review of it. And here's the IMDb photos page for it.
