I hope they leave Mephisto out of the Wanda/Vision story altogether in the MCU. Save him for that possible adaptation of Triumph and Torment. In any case I always thought that Wanda and Vision having children in such a bizarre manner even for comics was a mistake. Englehart's story just made Byrne go to work in again "fixing" something. Sometimes that works, sometimes it just makes things worse.
I won't post any spoilers about Victor's recent conduct in winning back Latveria but war is war. And one has to remember that the ones he's after also were responsible for the deaths of the 2000 workers in the Antlion station on the moon. But that's not to say Victor was also getting some personal revenge too for having been framed for the deed and being a fugitive for several weeks.
As for the Russo brothers interest in Victor, I couldn't find the Kevin Smith podcast where they appear. That is what I don't like about podcasts. First of all, they take up a lot of your time to watch, esp if you just want to find the part that you're interested in. They can veer off into other things, etc. And they can be hard to find or just disappear.
Here is an interview where the Russos briefly mention the unused Noah Hawley script for his proposed Doctor Doom movie. It's almost like fate is conspiring against Doom at this point. Just when Fox was on the verge of perhaps doing the solo movie, the corporation decides to sell off those assets to Disney. At least it appears he's in better hands there.
Agreed. The only thing that I think may change is his Romany heritage. Since he is a villain, they may want to avoid anything that would reflect negatively on the Roma. They juggled that very well with Magneto so perhaps the same can be done in the case of Doom.
