The Thirteenth Doctor could be...

[Bruce Banner]

Rumour is the new companion will also depart with Capaldi when he goes... Total fresh start for the next Doctor.

I still want them to cast Bill Nighy or Timothy Dalton.

[GlobalObserver]

My choice would either be David Hasselhoff or Don Rickles, and since Rickles just died, gotta go with David.

I'm still rooting for Clem.

They can't afford Hiddleston...maybe. His rate is around Cumberbatch and they were able to hold him for Sherlock. He would bring a massive draw.

It's not my show, but my choice would be Sean Bean. They've never had an action oriented guy play the role, right?

You know I never thought of Sean Bean in the roll before but I think it would be awesome.

He definitely could do the regeneration scene.

[hedrap]

^ ha. That was actually what made me think of him.

Then, an entire GoT/Whoverse fanfic community can be born!

Bean would be terrific, kind of a throwback to Pertwee.

[emeraldknight47]

Bean would be an excellent choice for a Doctor, with episodes and action-sequences likely more reminiscent of the Christopher Eccleston season than anyone's since.

[Earth 2 Chris]

Damn, I'm now in love with Sean Bean as the Doctor.

There are strong (but as yet unfounded) rumours that Kris Marshall will be the next Doctor.
I've pretty much never heard of him.

Twitter reactions flooded in after The Mirror reported that Kris, 44, has been hired to replace Peter Capaldi as the new Doctor. It comes after bookies took bets on whether the new Doctor would be a woman, notably Tilda Swinton or Olivia Colman. A source said: "Kris Marshall has already joined the cast and will regenerate at the end of this series, not in the Christmas special. They won't risk a woman Doctor. They want a David Tennant type.
Bookmakers have also suspended betting following a rush from punters. A William Hill spokesperson said: "Kris Marshall was well supported when it was announced that he was stepping down from Death in Paradise but he has been quiet in the last fortnight. The BBC has done well to keep it quiet and we will not be paying out until he/she is officially unveiled.

Adrian Paul or Michael Ironside.

I've heard some rumblings about this guy, but, yeah, I know next to nothing about him aside from the fact that he's younger than Capaldi, something I think the BBC wants to try to lasso back in the Matt Smith crowd.

[palitoy]

He's in his middle 40s, not sure Matt Smith is the right comparison.
