Doctor Who: Joseph Green, a politician taken over by a member of the Slitheen family in 2005's in 'Aliens of London / World War III'. Liked a good fart.

Game of Thrones: Bronze Yohn, aka Lord Yohn Royce, has dipped in and out of the series since its fourth season. Will no doubt be seen in the eighth.

Doctor Who: Another luminary possessed by a Slitheen. This time, the army's General Asquith.

Game of Thrones: The Dame picked up some Emmy noms for her recurring role as Olenna Tyrell. Sadly, she was poisoned by Jaime Lannister. Naughty boy.

Doctor Who: Starred alongside her real-life daughter (Rachael Stirling) in 'The Crimson Horror' from Mark Gatiss.

Game of Thrones: Lord Walder Frey came a cropper at the hands of Arya Stark in season six. Don't despair though, he was nearly 100 years old.

Doctor Who: Bradders popped in 2012's 'Dinosaurs on a Spaceship' (written by current showrunner Chris Chibnall) but more memorably made his mark as the First Doctor in 'Twice Upon a Time'.

Game of Thrones: The cruel Viserys Targaryen has been mentioned a few times since his golden demise in the first year of the show.

Doctor Who: A truly menacing performance as Jeremy Baines (or the transformed 'Son of Mine') in 2007's 'Human Nature / The Family of Blood'.

Game of Thrones: Played greenseer Jojen Reed. Kicked around for seasons three and four but was offed by his sister Meera in a mercy killing.

Doctor Who: Like Harry Lloyd, also starred in 'Human Nature / The Family of Blood'. Thomas played Tim Latimer, a boy with better than average telepathic abilities. Just like his GoT counterpart.

Doctor Who: Another almunus from Tenth Doctor ep 'Tooth and Claw'. He was after Queen Victoria and wasn't scared to use a werewolf to get at her.

Game of Thrones: Rodrik Cassel. After over a dozen appearances, he was executed in season five (after a few botched attempts, urgh).

Doctor Who: And another from 'Tooth and Claw'! He played a steward at Torchwood House but was killed by a werewolf.

Game of Thrones: Bastard blacksmith Gendry, a stalwart of the show since its start.

Doctor Who: Played Cline, a solder fighting against the duck-faced Hath in 'The Doctor's Daughter'. Was tricked by the titular character thus leading to her, the Doctor and Donna's escape.

Game of Thrones: Has appeared in every season since the second as Davos Seaworth and will be seen in the final next year. Whovians may note his first name is a bit Daleky-sounding.

Doctor Who: Captain Zhukov of Soviet submarine Firebird, which encountered a trapped Ice Warrior in 'Cold War'.

Game of Thrones: Plays Edmure Tully who, as far as we know, is not dead.  We assume he's still a captive of the Lannisters.

Doctor Who: A second 'Cold War' star, Menzies portrayed Lieutenant Stepashin on board the aforementioned Firebird. The story was written by Mark Gatiss; speaking of whom...

Game of Thrones: Envoy from the Iron Bank of Braavos, Tycho Nestoris. Will be seen once more in the final run of instalments.

Doctor Who: After writing two episodes, Gatiss finally got on screen in 'The Lazarus Experiment' opposite David Tennant's Time Lord. Mark continued to write for the show and was seen again under heavy prosthetics in 'The Wedding of River Song' and once more, with a moustache, in 'Twice Upon a Time'.
