The very last movie I saw was 28 Weeks later, which was awesome. One of the best action/horror movies I've ever seen.
In recent months I've seen Hardboiled(One of the best action movies ever), Cloverfield(A rather average movie that is saved by a cool concept), I am Legend(a good movie with the original ending, a crappy movie with the theatrical one), The Mist(fairly good horror movie), Donnie Yen's Flash Point(good martial arts crime drama, but Sha Po Lang a.k.a. Killzone was better).
I'm getting around to finally checking out The Bourne Supremacy movies soon. 3:10 to Yuma was great(Christian Bale is an awesome actor) and I loved Stardust(Michelle Pfeifer is still hot).
Those are my most recent movies, unless you count the director's cut of South Park's Imagination Land trilogy, which was fucking hilarious. You just can't beat watching Butters go through a battlefield yelling, "more spinach for Popeye, an M16 for Jesus!"
