Arthur Darvill has stated that he would "never say never" to a Doctor Who return.

The actor departed the BBC sci-fi drama last year, but told Digital Spy that he would be open to making a cameo in a special 50th anniversary episode.

"I'm so busy at the moment that I don't know if I'd be able to," said Darvill, who will appear opposite former Doctor David Tennant in ITV's new crime drama Broadchurch.

"But I'm very loyal to Doctor Who - I saw Steven Moffat recently and I think he's brilliant. He's one of those people that if he ever asked me to do anything, I'd do it."

Darvill also revealed that he had watched and enjoyed the Doctor Who 2012 Christmas special - the first episode to air following the departure of his character Rory.

"Yes, I did see that - I thought it was great," he said. "The show's constantly growing - it's quite nice watching it and not knowing what's going to happen!"

Broadchurch begins on Monday, March 4th on ITV.
