It’s been less than two years since Rwandan-Scottish actor Ncuti Gatwa was confirmed as the 15th Doctor Who.
His second series finale is set to premiere on BBC One on Saturday, May 31, with the feature-length episode also being screened in over 450 cinemas.
But there have been rumours that Gatwa may be leaving the TARDIS for good - with no third season yet confirmed by Disney and the BBC, who co-own the frachaise.
There’s even talk of it being the end of the road for the iconic series, which has been suffering from tumbling ratings.
Speculation has also been growing as to who - if anyone - might take over one of the biggest roles in British television.
Here are the 11 favourites, according to the experts at gambling.com.
