The end of Guardians of the Galaxy Vol. 2 heavily hinted at one Marvel's biggest cosmic characters - no, not Nova - Adam Warlock joining the on-screen roster.
While it may now be a tad too late for the character to take part in the Infinity Saga, even if he was an integral part of the comic book version, James Gunn's return to Marvel means that there will likely be some follow through on the thread set up in the previous entry.
How the character will be introduced among the chaos following Endgame and the added curveball of Thor now seeming as though he will be sticking with the Guardians (at least for now) is a mystery to everyone except Gunn himself. Due to how the Sovereign are the ones who have created Warlock however, we can presume that he won't initially be there to help.
Whichever way that ends up being done, what's for certain is that someone will need to play Marvel's so-called 'perfect man', and, with such a reputation as that, there are plenty of options as to who should do so.
10. Shazad Latif
Outside of Star Trek: Discovery, Latif's other works are not the most well known.
His character in Discovery is one of the most interesting and complex - due in no small part to his performance. Yet, because of how the actor has primarily been a part of TV projects, it seems that he has been overlooked for movie roles, even despite his talent and leading man look.
Latif would make a very good serious version of Warlock, his tortured character from the aforementioned Star Trek series being a good basis for a character who will presumably start off as a sort of antagonist and later turn into a full on hero.
Basically, Marvel should do what they do best and pluck a relatively unknown out of the shadow, and thrust them right into the spotlight.
