Behind the scenes
Wolverine appears on posters on Grant's wall in The Return of Doctor Mysterio. However, he is not identified by name.

While going undercover in 2020's Spyfall, Ryan Sinclair has second thoughts about his choice of alias, having gone with the name "Logan". He tells Yaz he's worried he looks "nothing like Hugh Jackman". This is in reference to, the 2017 Marvel film in which Hugh Jackman starred as Wolverine.
