DOCTOR Who's iconic sci-fi shoes have been filled by no less than 13 actors in its TV history yet David Tennant and current star, Jodie Whittaker, are pitching for the top Time Lord spot.
The actors were seen getting stuck into some hilarious banter over who best played the futuristic role, during an interview with Last Late Show host James Corden.
Gavin and Stacey star James fronts the US chat show, and told how American audiences will now be able to see the BBC programme in its entirety on its new home, HBO Max.
Quzzing the stars on the best place to start Jodie, who is the first female Doctor, replied: "You're going to get, on HBO Max, seasons 1 to 11. Start with season 11,” referring to the one in which she stars.
Almost immediately David, who played the Time Lord for three series, interjected: "I'd go with (season) 2.
"Around season 2 is where it really comes alive, I'd say."
A giggling Jodie then spoke directly to James as she quipped: "I think when you introduced us, you gave me top billing.
"It didn’t go unnoticed, babe. You said 'Jodie Whittaker' first."
Yet not letting the banter lie, David replied: "I think I got an 'and'. And that's sometimes better."
Laughing along with the TV favourites, James directly addressed his chat show audience as he said: "What you're watching right now is two brilliant actors who have been starved of attention for three months.
"With the slightest glimpse, it's become about billing and status."
David later told how playing a part of the UK's "cultural heritage" was in fact a "double-edged sword", as he wanted to get the character spot on.
Meanwhile, there could soon be another name thrown into the top Time Lord hat.
Jodie, 38, has confirmed she will be back for season 13, which has been thrown into chaos during the coronavirus pandemic.
