Capaldi is the bookies favourite to take the job, and its not hard to see why. A high-calibre television actor who occasionally rocks up in films he was most recently spotted in World War Z Capaldis career sees him occupy that coveted halfway-house of an established-yet-available name that Whos producers might seek as the safe option. He wouldve also done the tried-and-tested route of taking a minor part in the show beforehand, having played Roman father Caecilius in the critically lauded Fires of Pompeii coincidentally an episode which saw Karen Gillian cameo as a soothsayer and took a part in the ridiculously awesome Torchwood Children of Earth. Hell be known to at least some of the crew, making for an easier transition. Yet what might be Capaldis biggest strength his status in the TV world might also be his biggest weakness. Simply put, Capaldis most famous role is that of foul-mouthed spin doctor Malcolm Tucker in The Thick Of It, and I dont think the foul-mouthed invective of the worlds angriest Scot will ever be allowed near a family friendly TARDIS. However, I really hope that they have an outtake of him screaming get the f**king f**k in the f**king TARDIS for f**k s sake. If they didnt, itd be one hell of a missed opportunity. Yet regardless, Capaldi is a very capable actor who possesses that intellectual streak so vital to the Doctors characterisation and it also might be nice to have an older Doctor in the part, especially after the positively boyish Smith.
