5) Caliban
Ricky Gervais’ frequent comedy partner, Stephen Merchant, gives a rare dramatic performance in Logan as albino mutant Caliban. Fans who know their stuff will remember that Caliban previously appeared in X-Men: Apocalypse, as played by Icelandic/French actor Tomas Lemarquis. The varying depictions of Caliban are one of the main reasons why Logan must take place in a slightly alternate timeline from the other movies, as confirmed by James Mangold.
There is some crossover between the two, however. Donald Pierce talks to Caliban at one stage and references how he used to be on “our side.” This is perhaps a nod to Caliban being a shady underground broker in Apocalypse rather than the good guy aid to Charles that he is in Logan. The idea that Caliban’s a bad guy gone good is also a reverse of his situation in the comics. At first, he was an ally to the X-Men but later became one of Apocalypse’s Four Horsemen.
