John Krasinski shouldn’t play Jimmy Woo. They shouldn’t cast him just bc the internet wants them to. Also, John Krasinski is already in the MCU. He plays Jimmy Woo in Ant-Man and the Wasp and WandaVision.
Seriously though, we don't have that much to theorise on and are mainly just looking at the year ahead rather than further in the future. We're all excited, just it's not really that close at the moment.
The 1st family is going too be great and to theorize it know could be exciting however no mention or inspiration for them yet in the mcu other than a possible Easter egg in far from home doesn't matter persay. I truly wish there was theories or conversations. I hope instead on og op OP villain doom they go with the mole man 1st movie just my hope's.
I'm still pushing for John Krasinski and Emily Blunt for Mr. Fantastic and Invisible Woman, Zac Efron as Human Torch, and I haven't decided who should play Thing.
