The positive reception from Luther fans got us thinking - are there characters in other shows who deserve their own spinoffs? This week's Friday Fiver nominates a few serious - and a few not so serious - candidates...
Canton Everett Delaware III (Mark Sheppard) from Doctor Who
Mark recently told us that he'd love to reprise the role of ex-FBI agent and all-round bad-ass Canton on Doctor Who, but why not go the whole hog and give him his own spinoff show?
Sheppard is hugely popular with cult and sci-fi fans, and a '60s-set Canton series - think The Avengers with more of a sci-fi slant - sounds like a tantalising prospect to us...
Schmidt (Max Greenfield) from New Girl
Even leaving aside the huge number of possible pun titles that the character's name allows (Piece of Schmidt? Schmidt Happens?), Greenfield's womanising funnyman is just too awesome a character to be contained within Zooey Deschanel's kooky sitcom alone...
We want to see what Schmidt gets up to away from Jess, Nick and Winston - watch the accompanying video below to see just how awesome a spinoff series could be...
Virgil (David Marciano) from Homeland
We here at Tube Talk have a soft spot for Virgil, so we'd love to see him in his own series - we're picturing a comedy drama, in which we discover what the bumbling surveillance tech gets up to when he's not spying on Brody (Damian Lewis)...
Maybe Virgil runs his own shoddy private detective agency and is somehow able to foul up each case that comes his way? Claire Danes (Carrie) could make a cameo appearance at the end of each episode to deliver her exasperated catchphrase: "Jesus Christ, Virgil!"
Castiel (Misha Collins) from Supernatural
Of late, poor Cas has played a relatively small role in the lives of the Winchesters. Even Misha Collins himself has admitted that the "incredibly powerful" angel poses a plot problem for writers, since he "solves too many problems too easily for Sam (Jared Padalecki) and Dean (Jensen Ackles)".
So why not spin Cas off into his own series? Given the character's amazing abilities, Castiel could afford to be a little more epic and fantasy-based than the more grounded Supernatural. We'd definitely tune in.
Darren Lamb (Stephen Merchant) from Extras
Alright, so Ricky Gervais and cohort Merchant might have ruled out any more Extras, but why not a follow-up show that explores the world of the hapless Darren Lamb and his sidekick, bumbling Barry (Shaun Williamson)?
Lamb's humdrum life is so far removed from the glitz and glamour of stardom that this new show would have no problem remaining distinct from its parent series. Merchant recently signed up to develop new sitcom Hello Ladies for HBO - fingers crossed that the new show can recapture a little of that Darren magic.
