Simon Pegg has revealed working with the Monty Python stars is a dream come true.
The World's End star has started filming Terry Jones' upcoming comedy alongside Michael Palin, Terry Gilliam and John Cleese, as well as Kate Beckinsale, Joanna Lumley and Robin Williams.
"I'm in the midst of shooting that at the moment, so it's a lot of fun," he said.
The actor added: "It's very nice to be working with those guys, because they are responsible for my own interests in comedy to a certain degree."
The film follows a disillusioned school teacher (played by Simon), who suddenly finds he has the ability to do anything he wants, which was bestowed upon him by a group of power-crazed aliens watching him from space.
Kate Beckinsale said she signed on immediately when she was approached about her role.
"I think if you love British comedy, it's kind of a no-brainer to be around those people," she said, adding that her character is "somebody who lives in the flat below Simon Pegg".
The Underworld star is also appearing in Michael Winterbottom's drama The Face Of An Angel, which stars Cara Delevingne as Amanda Knox, who was accused of Meredith Kercher's murder.
Kate said she was the model co-star: "I really liked her a lot, (she's) a good girl. She was really professional and cool and a really nice person."
