The 53-year-old actor starred as the leader of the First Order in 2015's 'Star Wars: The Force Awakens' and has reprised his role in the anticipated eighth instalment 'The Last Jedi', helmed by Rian Johnson.

Serkis insists his evil alter ego is a very powerful individual in the 'Star Wars' universe and is "more dangerous and despicable" than the Sith Lord, who was Emperor Palpatine's apprentice.

At the world premiere of the new movie in the Shrine Auditorium in Los Angeles on Sunday (10.12.17), Serkis said: "I think Supreme Leader Snoke would say he's more powerful than Darth Vader, but he's an egotistical narcissist. So yes, I think he believes himself to be so, and thinks that this is his divine right to be the leader. He has limitless resources and has massive military capability, which isn't working, and that's deeply frustrating. There's this sense of feminine force and energy that's coming towards him that seeks to undue him, which is terrifying. He feels vulnerable and he will do anything to stop it, which makes him even more dangerous and despicable than Darth Vader."

Serkis returns in the saga along with cast members John Boyega (Finn), Daisy Ridley (Rey), Adam Driver (Kylo Ren), Oscar Isaac (Poe Dameron), Lupita Nyong'o (Maz Kanata), Gwendoline Christie (Captain Phasma), Anthony Daniels (C-3PO), and Domhnall Gleeson (General Lux).

The film also sees the return of Mark Hamill as Jedi Master Luke Skywalker and Carrie Fisher in her last appearance as General Leia Organa following her death last December at the age of 60.
