Alien comedy 'shows geeks are cool'
Simon Pegg, Sigourney Weaver and Nick Frost arriving for the world premiere of Paul at the Empire Leicester Square, London
Simon Pegg and Nick Frost have proved it's cool to be a sci-fi nerd at the premiere of their new alien comedy Paul.
The Hot Fuzz pair walked the purple carpet in London's Leicester Square, along with Sigourney Weaver, who makes a cameo in the film, signing autographs for screaming fans in alien masks.
Simon and Nick co-wrote the film about two geeks on a pilgrimage to America's UFO heartland, where they accidentally befriend an alien on the run from a secret military base and agree to help him escape to his mother ship. The pair enjoyed a road trip of America together and watched hours of science fiction films to get inspiration for the film.
Simon revealed: "We did the road trip initially as a way of getting a free holiday out of Universal but it was an incredibly inspiring time and a lot of what happened on that trip, we fed into the script. It was a great adventure."
Nick added: "It is work but you're also with your best mate, Sigourney Weaver's there and you're driving an RV in the desert and it's beautiful and the food's great, too."
Alien star Sigourney insisted she enjoyed working with the British pair just as much as they did with her.
The 61-year-old actress said: "I'm a huge fan of theirs too, so once we all got over our excitement - I think there's a great deal of warmth and innocence in this picture."
Simon added: "I think that's becoming more and more apparent these days that being a geek is just about being an enthusiast and not being embarrassed by that."
