I finally watched the two Fantastic Four films that came out a few years ago. I wound up with both DVDs for less than 4 bucks. There didn't seem to be any urgency to see them when they were new, I wasn't going to see them at the theater, and that was about when I quit buying a lot of DVDs as they came out. The price of a new release was falling faster than it had the first years of the format and I could wait 6-12 months and pay less than half the release price. Plus a popular title was going to be in the used venues pretty quick.
There is a 1994 low-budget film called The Fantastic Four that Roger Corman produced. Some say it was a trick to keep the film rights and it was never meant for release to the general public. I don't know but it never did get released. You can find bootleg copies out in the world but since it's not very good, there's not much point in seeing it. If you're curious, you can see it on YouTube for free. You'll only have wasted that time you spent watching it.
Fantastic Four came out in 2005 and it's pretty much a typical origin story. It's not quite like the comic, they pack everyone into Victor Doom's Space Station to observe a space cloud that is passing near the Earth. Everyone gets their new powers from the cloud and there's a lot of melodrama as they deal with that. Victor Von Doom turns to metal and after some business upsets he turns to evil when he kills off the other board members. There's conflict there. Eventually it ends with the team a real team and Victor banished to the country of his birth. It's way better than the 1995 film but it still didn't make me go Yahoo! Like all Marvel films the level of melodrama is high and that detracts, at least for me, from the fun of the story.
The Fantastic Four return in the 2007 sequel Fantastic Four: Rise Of The Silver Surfer. The melodrama here mostly hinges on the marriage of Reed and Sue. It nearly doesn't happen when the The Silver Surfer comes to scout out the Earth as a possible lunch for the planet chomping Galactus. I didn't care much for the film's depiction of Galactus as a big swirly cloud. I liked the old comic book version better. There's plenty of interaction with The FF, the SS, and Doctor Doom. Obviously the planet is saved, the studio had hoped for a third Fantastic Four and a separate Silver Surfer movie. The box office was fine on FF:ROTSS but the studio didn't think it was quite good enough for a sequels.
Of course there was a 2015 re-boot of the Fantastic Four but I sure didn't care that much for it. I wouldn't want to watch it again. I might watch these the two older films again, I have the DVDs, and who knows, it might happen.
