"I think there was a petition online to get me involved in Doctor Who. I'm not a Doctor Who fanatic but I am a Steven Moffat fanatic.
"I've worked with him on Jekyll and Coupling so if he was to write anything for me - not just Doctor Who - I'd drop everything to go and do that."
Bellman currently appears in Leverage, which airs Wednesdays at 9pm on Bravo.
