Okay, we need to officially shut down this whole Cap vs. Wolverine thing, as if the fact that Wolverine outgrossed Cap is a testament of its staying power.
It actually reveals the exact opposite. Behold:
X-Men Origins: Wolverine= $373,062,864
Captain America= 368,608,363
Okay. Am I the only one who sees how f***ing close these numbers are? That's damn disturbing.
By the time XOW came out, Wolverine had been the lead for three
of set-up. Next to Spider-Man, he is hands-down Marvel's most popular male character and always has been (he's in every goddamn comic book, even non-X-Men titles, plus his own multiple titles). His film featured appearances from kid Cyclops, Emma Frost, Baby Storm, Gambit, Deadpool, every frigging mutant cameo of all time.
Now, let's look at Captain America by comparison: significantly lesser known and yet his first film (one that came without any set up, no trilogy, etc.) came within spitting
distance of Wolverine's first "solo" film. That's on "What the hell" levels, people.
