* HeyItsThatGuy:
** [[Series/GarthMarenghisDarkplace Moss is Thornton Reed and Douglas is Dr. Lucien Sanchez]]. The chick who dumps Roy for having shit smeared on his head is also Dr. Liz Asher, while Richmond makes a one-off appearance as a rabid gorilla in the same show.
** Also, [[TheInbetweeners Will's mum]] is Douglas's estranged wife Victoria, and the Vicar at Denholm's funeral is Neil's Dad.
** [[TheMightyBoosh Moss is also Saboo, Douglas is Dixon Bainbridge and Richmond is Vince Noir]].
** Female Sulu and Ivana are played by GemmaChan, who is also [[Series/DoctorWho Mia Bennett]] and [[SecretDiaryOfACallGirl Charlotte]].
** Moss' Psychiatrist who reminds Roy of his mother is [[Series/DoctorWho Madame Kovarian]].
** And of course, Denholm was previously an [[Series/TheDayToday aggressive, Paxman-like news reporter]]. In fact, physically, the moustache is the only thing different.
** Derek Pippen is [[Film/ThePhantomMenace Nute Gunray]] [[Film/AttackOfTheClones and]] [[Film/RevengeOftheSith Ki-Adi-Mundi.]]
*** Also [[Series/DoctorWho the Ood]]!
* HeyItsThatVoice: "[[LampshadeHanging I don't think that's Elton John]]" -- Well no, because it's [[Music/TheDivineComedy Neil Hannon]].
* WhatCouldHaveBeen: An American version was planned and a pilot was shot, but not picked up. The biggest effect would have been Joel [=McHale=] passing up {{Series/Community}} for it.
