10 Castings For Upcoming Movies That MUST Happen

10. Nikolaj Coster-Waldau - Adam Warlock (Guardians Of The Galaxy Vol. 3)

Though there certainly aren't any guarantees that Adam Warlock will appear in Guardians of the Galaxy Vol. 3, the character's existence within the Marvel Cinematic Universe was confirmed at the end of the second film, and writer-director James Gunn has since stated he will play an important role in the MCU's future.

Assuming that Adam Warlock does appear in Vol. 3, however, casting the ultra-charismatic space-messiah rock-god won't be easy.

Zac Efron's name has been bandied around a lot online, though one suspects that at this point his casting would simply be too obvious and pat for Gunn to actually pull the trigger.

But a more interesting possibility comes in the form of Game of Thrones star Nikolaj Coster-Waldau. In addition to bearing a strong physical resemblance to the comic book Warlock, we know he's got what it takes to play a charming a**hole.

It's an extremely tough part to cast, but Coster-Waldau offers up the best of both worlds - cheeky suaveness and dramatic stoicism when the time calls for it.
