Although details about the project are awaited, Geeks Worldwide claims that Marvel has been holding "virtual meetings" with actors, directors and writers lately, and Krasinski was one of them, reports dailymail.co.uk.
The report also stated that they are not sure if Marvel was interested in Krasinski as an actor, writer, director, or all three.
It also indicates that Krasinski might be in talks for a role as Young Avengers. Another possibility that the site mentioned is "Fantastic Four" reboot with Disney in control of the franchise due to the Fox merger.
Marvel has not confirmed any developments with Krasinski, and the actor hasn't responded to the report either. A post shared by (@johnkrasinski) on Mar 30, 2020 at 9:20am PDT Krasinski
