I don't know if you've noticed, but Daisy from Spaced is the same chick from Shaun of the Dead, the one who he runs into on the street. Also, when they're all passing by each other, the bizarro mom is Marsha from Spaced. Annnnnnnnnnnddddddddd....... On the special features you can see The Rave Guy (can't think of his name) is one of the zombies. It's quite hilarious.
