The 44-year-old actor played Obi-Wan Kenobi in 1999 movie Star Wars: Episode I - The Phantom Menace, 2002's Star Wars: Episode II - Attack of the Clones and Star Wars: Episode III - Revenge of the Sith in 2005, so when it was announced they were making a new instalment in the franchise, Ewan thought his involvement in the project was a given.

But it took some time before he was contacted by director J.J. Abrams and asked to voice a line in the film.

"It was very late in the day - I'd been waiting for the call to come for two years, you know," Ewan laughed to talk show host Jimmy Kimmel on Thursday night (28Jan16). "I was thinking, 'Maybe they've lost my agent's phone number or something!' And then I got a call just shortly before it was released from J.J., and he called me and said, 'I'd love me to be part of it and in it, and there's a sequence where we can use your voice, where you hear Obi-Wan Kenobi's voice coming from the distance reaches of the force'. And I was like, 'Yeah, I'd love it be in it - I've just been waiting for your call!' And I went in and I was able to see some of it before anyone else had seen it and I was very impressed and I recorded a line for it."

It wasn't just Ewan's voice that was used for the line, however. Late actor Alec Guinness, who portrayed the Jedi Master in 1977's Star Wars: Episode IV - A New Hope, 1980's Star Wars: Episode V - The Empire Strikes Back and Star Wars: Episode VI - Return of the Jedi in 1983, was also involved in the newest film.

"The line is, 'Rey, these are your first steps,'" Ewan explained. "But they got Alec Guinness to do the 'Rey'. They got a line of him as Obi-Wan saying 'afraid', and they cut the 'a' and the 'd' off so he's saying 'Rey'. So Alec Guinness says, 'Rey,' and then I say, 'These are your first steps.'"
