If any fans of Simon Pegg have watched Shaun of the Dead and Hot Fuzz, they may notice a small similarity between the two. The fact that Simon Pegg has starred as the main character with Nicholas Frost as the sidekick is only a little thing. They are actually part of a 'Blood and Icecream' trio.
They both have blood in them and in Hot Fuzz there is a blue cornetto (police colour) and in Shaun of the Dead there's a red one (blood). And now a third one is going to come out called The World Ends, a sci-fi movie. Presumably the cornetto will be green (alien?).
