Meeting the international press to promote his latest movie, The World's End, at Claridges Hotel in July in London, the Brit made the proclamation while agreeing that he might have been typecast as the underdog in Hollywood movies.
He said with a hearty laugh: "You play to your strengths. I wind up playing Benji in Mission: Impossible because that role suits me, and Scotty in Star Trek because that is kind of what I can do quite well.
"Hopefully, I won't do that forever, but if it means I can participate in these fantastic films, I'm quite happy to be the underdog."
Pegg began his career as a stand-up comedian, and very often brings his comedic roots to his film roles.
The 43-year-old said: "Films like Mission: Impossible - Ghost Protocol and Star Trek: Into Darkness are whammed so tight with tension that you need to release it every now and again, and the audiences drink up comedy like thirsty people needing water."
Pegg reunites with writing partner and director Edgar Wright and long-time collaborator Nick Frost for The World's End, following their hits Shaun Of The Dead (2004) and Hot Fuzz (2007).
In its UK opening weekend, the trio proved they have still got the box-office Midas' touch when The World's End raked in £2.1 million (S$4.2 million), beating the £1.6 million opening from Shaun Of The Dead in 2004, but falling behind Hot Fuzz's £5.9 million haul.
The World's End, which opens here on Sept 19, is about five men revisiting a teenage pub-crawl drinking marathon, 20 years after the first attempt failed with disastrous consequences.
