Clarke, who played Rose Tyler's boyfriend Mickey Smith, revealed that he would not mind joining Freema Agyeman in coming back to the show.
Agyeman is reportedly going to return as Martha Jones in one of the upcoming specials being screened this year.
Clarke told The Sun: "Who would turn down a return to Doctor Who? I love the show and have always supported it. I was there from day one when nobody was sure if it was going to be a hit.
"But the show moves on. Who knows? Whatever happens, happens."
He added that he will see if the programme writers "come knocking".
The actor-director recently told DS that he tries not to have an ego despite his recent Orange Rising Star BAFTA nomination.
