Sir Ian McKellen, who played Gandalf in the Lord Of The Rings trilogy, will make a cameo appearance in the new Guillemots video.
The English actor, who admits to being a fan of the group, filmed his guest spot earlier this week.
"A young relative of mine, who's a fan of the Guillemots took me along to a concert of theirs in London and I really took to them, I really liked the music," Sir Ian told Sky News.
"I heard about this video for the new song, which I really like and I happen to have nothing better to do, and it's quite near home, so I dropped in, and here I am."
The video is for the second single to be taken from the band’s second album, ‘Red’, which was released on Monday (March 24th).
