Matthew McConaughey has been teasing involvement with both Marvel and DC for a while now when he revealed that he has read scripts from both studios. The most popular rumor is that McConaughey was being prepped for the part of Norman Osborn, the secret identity of the Green Goblin.
However, according to recent news, he was never in talks for Green Goblin. In fact, he was never intended to be a part of the rebooted Spider-Man films at all. Instead, McConaughey was offered a role that you might say is "out of this world!"
Okay, bad puns aside, Matthew McConaughey recently revealed that he turned down the role of the currently mysterious lead villain of [Guardians of the Galaxy Vol. 2](tag:1081113). Though he did not reveal why he didn't take the role, the offer of the part alone tells us a little about Marvel's plans for the character.
Instead of bringing lesser known gems to the spotlight like he did with Chris Pratt, director James Gunn seems to be looking for more high-end, mainstream talent for this role. That's exciting to hear because, no offense to Lee Pace, but Ronan the Accuser from the first Guardians film was lacking a bit in the supervillain department.
Though one of the most speculated villains is Star-Lord's father, Gunn basically shut down those speculations by stating that he's changing the father-son relationship as to not rip off the Star Wars plot. If not Quill, Sr., then who? All we know so far is that the villain is male, and that they are going to need some serious acting chops.
Well, aside from Norman Osborn, McConaughey has also been the popular fan choice for a Marvel cosmic character, although he doesn't necessarily appear to be a villain. This of course would be Adam Warlock, who has a substantial part in both the Infinity Gauntlet and Infinity War comic storylines.
Though Warlock may have been an ally to both the Avengers and the Guardians in the Infinity Gauntlet catastrophe, he has had some villainous moments as well, especially as Magus, his incredibly evil alter-ego.
In the comics, Lord Chaos and Master Order took the alternate Warlock and taught him dark secrets that he could become a champion of life, to counteract Thanos's actions as a champion of death. He went on to conquer entire planets and start an intergalactic empire that would put Darth Vader to shame.
Magus would be a perfect villain for Guardians of the Galaxy Vol. 2 for a variety of different reasons. For one, the character already has ties to Thanos, who is continuing to become the focus of the Marvel Cinematic Universe. He would bring a character that fans have been clamoring for (Adam Warlock), and show all sides of him. That would certainly make for a more engaging villain than Ronan.
That would also explain the casting decision that Gunn was shooting for. Sure, with a character like Ronan, who movie-goers aren't very familiar with, you could cast a lesser-known actor like Lee Pace. However, Adam Warlock is a huge character in the Marvel Universe, and he deserves only the best in acting talent. McConaughey has time and time again shown his acting prowess and could have made for a good Warlock.
There are many other cosmic villains in the Marvel comics, varying from Kang the Conqueror to Galactus, and we're just going to have to wait for some more news before we actually know who will be facing our Guardians next.
