This is one of my favorite movies. This movie is great as it's lead by the two comedic geniuses playing Shaun and Ed, Simon Pegg and Nick Frost, (Pegg also co-wrote the film). It's a great parody on the recent zombie movie trend (obviously the Dawn of the Dead remake is the main reference, but if you listen at the end, they make fun of 28 Days Later too). Very clever film-making and excellent comedic moments as well as more serious ones. If you love zombie movies and British comedy, you're in for a big treat! Wonderful supporting appearances by Jessica Hynes as Yvonne, Bill Nighy as Philip, and Penelope Wilton as Mum.
(In a bit of trivia, Jessica Hynes, Simon Pegg, and Penelope Wilton have all guest starred on the new Doctor Who series.)
