Sean dresses as his father for Halloween and the resemblance is uncanny. Fantastic photo for me since Jon is my favourite Doctor. I can only hope one day Sean gets a part in Who, it's long overdue.

That really is excellent!

Sweet heavens, someone get him on screen. He is truly the real deal!

It's amazing! The spiders didn't get him after all.

If the Beeb does a sequel to An Adventure In Space and Time then Sean should definitely play his dad

Who took the photo ??

Great all the same though

Oh WOW!

As a fan of both Pertwees (Sean from Dog Soldiers through to Elementary and Gotham), I'd love to see him sometime. Will never happen though. Watched Inferno recently for first time and loved the whole alt universe element.

Is this a production still from the Christmas episode?
