The third and final instalment in the Guardians of the Galaxy trilogy is finally upon us.


Guardians of the Galaxy Vol 3 sees the return of the eponymous team – Star-Lord (Chris Pratt), Gamora (Zoe Saldana), Nebula (Karen Gillan), Drax (Dave Bautista) and Rocket (Bradley Cooper) – alongside several new faces.

These include British stars Will Poulter as Adam Warlock, a popular character from Marvel Comics, and Chukwudi Iwuji as brand new villain the High Evolutionary, whose evil plan is linked to Rocket's previously unexplored backstory, which is revealed over the course of the new film.

Of course, some of the returning cast – such as Bautista – have already announced that this will be their last appearance in the MCU, but for now, they're still very much part of things.
