Tom Cruise is busy right now filming Top Gun: Maverick, so he wouldn’t be able to jump into the movie right now anyway.
Christopher McQuarrie is clear that the movie is being actively worked on, it’s not sitting on an empty shelf someplace being forgotten about.
However, while we may not be getting the Edge of Tomorrow sequel any time soon, it does still appear that the plan is to get it at some point.
Although, the actor’s schedule appears to be mostly open once that is done, and we’re also not aware of anything big that Emily Blunt is working on, having recently wrapped filming on Disney’s Jungle Cruise, so we may actually be coming into a good moment in time to film Edge of Tomorrow 2, assuming everything else is ready to go as well.
