You'll both totally dig it then. It feels a little more Hollywood like Snatch (compared to Lock Stock), with a little bit of polish to the characters like in Layer Cake.
Don't even get me started on the zombie genre. Shaun of the Dead, 28 Days Later, and Dawn of the Dead (remake) are some of the newer classics IMHO. Read World War Z if you really are into the fun of it all.

Fun trivia for the zombie film lovers: The quote from Night of the Living Dead, "They're coming to get you, Barbara." is used in the Shaun of the Dead when Shaun and Ed are talking with Shaun's mom on the phone. "We're coming to get your Barbara!" :thumbup:
And... Simon Pegg and Nick Frost (from SotD) snagged bit parts in Land of the Dead because they are such huge fans of George Romero (and all of his films) and because (of course) they made the cult classic Shaun of the Dead. They played two zombies tied up at a club where people threw stuff at them.
