Let's not forget about the MCU before it was... well, the MCU!
Captain America 1990: Steals a car scene. This is actually pretty funny.
Dr Strange 1978
Fantastic 4 1994! (Tho some would argue it might be the best one, lol)
All of those are so bad they're good! I've actually watched them all too, and they were all made on shoestring budgets. I think Fantastic 4 was definitely the most entertaining. It has an entertaining back story too. It was never meant to be released and was rush made solely to retain the movie rights. At the end of it the studio actually paid a lot of money to not have it shown. There's a lot more to it, and an interesting story in itself if you look it up.
The cast and crew however, had no idea and thought they were shooting a legit superhero movie and you can tell. As bad as it is, it has heart and you can tell everyone was trying. It's arguably the most comic book accurate Fantastic 4 of them all, and it's
definitely the best portrayal (if maybe the goofiest) of Dr Doom we've seen on film!
