Yeah I'm just not sure of RDJ being Doom. He's too entwined with Tony stark I think. My personal pick would have been Rhys Ifans as I don't think anyone remembers him as Curt Connors in Andrew Garfield's Spiderman.
I think it is sill with RDJ, but I hope it is not a Tony Stark variant but he spends hours in the makeup chair when not wearing the mask to have a disfigured face
saved? yes. marvel was never going to surpass the success of phase 1 to 3 with that new avengers group. disney ruined phase 4. now they can expand the MCU with a new epic featuring the fantastic 4 and a new threat in dr doom. why RDJ tho? seeing tony stark as dr victor von doom will be... weird(?) if RDJ was coming back i would have thought black panther lol
