According to Iger, while Avengers 4 will be conclusive, there are likely going to be more installments in the future.
Don’t expect to have Avengers 4 be the last Avengers movie we ever see.
Bob Iger added, “Given the popularity of the characters and given the popularity of the franchise, I don’t think people should conclude there will never be another Avengers movie.”
The other interesting bit to tackle here is this new franchise Bob Iger speaks of.
