John Simm would be happy to reprise his role as the Master in 'Doctor Who'.
The Radio Times said the star, who played the Doctor's arch-adversary between 2007 and 2010, would like to return but make the character even darker.
"I'd love the opportunity to play him differently," he reportedly told the Cheltenham Literature Festival. "I'd love to have another take on him, to be a bit quieter."
Simms's alter-ego in the sci-fi series was known for his manic laughter.
But Simm confessed: "I started annoying myself after a while. Russell T Davies had a specific idea of what he wanted him to be like. So I just had to do exactly what he wanted me to, and he wanted a giggling lunatic."
He said of Russell's successor Steven Moffat: "There's a new writer now and I'm sure his take on him would be different so I'd be interested to have a look at it. I'd like to take the Master to a very, very dark place."
