Notes:
Requested ages were for Peter and MJ to be mid 20s (because JMS’ run was the request).
I firmly believe the best casting job in any comic book movie was JK Simmons as J. Jonah Jameson so he stays.
Also the person who requested this didn’t ask for Black Cat but I threw her in for fun which is why she’s listed last.
always reblog my fan casts from my personal here
