As much as I find Shawn Levy to be a bland director, he’s probably an ideal person to direct these big Marvel “event” films. By all accounts, he’s pretty reliable and knows how to play ball. He also already has experience working with Ryan Reynolds, as well as handling big ensembles.
As a matter of fact, assuming DP3 is well received, I would expect them to get Levy for at least one of the upcoming Avengers films.
