Oh sure, maybe Ant-Man and the Wasp will accumulate more money than Ant-Man (it is a Marvel movie, after all), but it’s doubtful it will be at Guardians of the Galaxy Vol. 2’s level.
No offense to Scott Lang and Hope van Dyne, but compared to the Guardians, it’s hard to imagine the shrinking heroes performing that much better at the box office.
Given how obscure the Guardians of the Galaxy were obscure even by comic book standards pre-2014, the fact that their first movie performed as well as it did commercially came as a shock, though certainly not an unwelcome one.
Since November’s Thor: Ragnarok is another threequel, the next opportunity for this sequel (second movie) increase to be surpassed will be when Ant-Man and the Wasp comes out next summer.
