The 45-year-old actor - who plays the role of junk dealer Unkar Plutt in the forthcoming flick 'Star Wars: The Force Awakens' - likes 'Star Trek' more because he's contributed to the script for the third film in the rebooted series 'Star Trek Beyond'.

Pegg - who played Enterprise engineer Scotty in the previous two films - said: "I am bi-starrial. It's a choice I don't want to make ... But it has to be 'Star Trek' now because I've written part of it but 'Star Wars' was a huge film for me growing up."

Elsewhere, the 'Mission: Impossible' star revealed how "nervous" Tom Cruise was when he hung off the side of a plane for 'Mission: Impossible - Rouge Nation' and joked that he's "worried" what dangerous stunt he's going to attempt in the next instalment.

Speaking on the 'Jonathan Ross Show', he said: "Everybody was very nervous that day including him, you don't usually see him nervous. He was focused but he looked like he was bricking it!

"I worry about what's he going to do now and we've had this conversation a few times, 'Seriously though what are you going to do now?' Because we're going to make 'Mission: Impossible 6' - I don't know if I'm in it yet but fingers crossed - but literally what is he going to do? Jump off the moon?' I'm worried about him, I think he could seriously hurt himself if he's not careful!"
