Simon Pegg brought a distinct blend of humor and humanity to Star Trek with his portrayal of Montgomery "Scotty" Scott in Star Trek (2009), Star Trek Into Darkness, and Star Trek Beyond. His take on the ship’s beloved engineer reimagined the classic character originally played by James Doohan, adding a modern edge while honoring the spirit of the Enterprise’s technical wizard. Pegg also contributed as a co-writer on Star Trek Beyond alongside director Justin Lin, helping to deepen the story and character dynamics, including Captain Kirk and Spock’s evolving friendship. Outside Star Trek, Pegg is widely known for his work on the Cornetto Trilogy and as Benji Dunn in the Mission: Impossible series, but it is his role as Scotty that has become a favorite for Star Trek fans worldwide.
