I don't understand people's insistence on Galactus looking exactly like he does in the comics just because it's in the comics. It doesn't make sense for him to be a giant purple man. It's fine in the comics, not the movie which should be grounded. A creepy, disturbing organism or like Zarex said pure energy would make more sense than a giant man in a purple suit.
Galactus doesn't even need to look like a man. His only purpose is to devour worlds. He barely talks and when he does it's ALWAYS about how he needs to eat more worlds. It would make more sense to have him look like an organism with no purpose other than to devour, like amoebas, than to make him a giant purple guy.
but the giant purple man is just so rad.
i actually agree pretty much, because it's really more up to the story itself as to whether he works as a threatening villain.
Like in FF2, if they'd just replaced the big cloud with a real comic book Galactus, that wouldn't have suddenly transformed it into a far better movie. Actually, if they'd done that, can you imagine how much more ridicule and endless complaint we'd be hearing about it still? it would be held up as maybe one of the worst things to ever happen in comic book film history, by us and by everybody out there, the half-imaginary 'general audience'.
Cloud Galactus didn't work cuz the movie just wasn't written well. I have to go back and rewatch that one and try to break it down to what's truly wrong with it. But it wasn't Cloud Galactus.
I think tho, that having an amorphous being, like a cloud, blob of matter, energy, amoeba type of thing, is not really ever going to capture the threat that Galactus presents. It could be suit the movie fine, and it avoiids the bigger problem of making him giant purple man, but it's never gonna acheive the glory and terror of pulling off the giant purple man. you know what I mean?
The whole threat of something coming and eating an entire world is actually destruction so enormous that it turns out to us as not being scary at all. This happens in comic books whenever they talk about a whole dimension or a universe being wiped out. To me, it's just really easy to not process that, it's like that translates to me, 'okay, this guy is supposed to be really bad, is what they are saying. i get it, he's a villain.'
but it's far less scary or evil than a villain that kills one person or destroys a downtown of some city.
so you've got this semi-abstract threat of the whole planet being eaten, which you could make more real of course by showing it begin to happen to individuals and different other obvious things, but at the root of it, it's a semi-abstract threat. and then using a thing like an amorphous mass, even if it looks vile and scary, I think that just plays to the weakness of this abstraction.
the tree type thing that you posted is better than an amoeba, but I think that what's truly terrifying is if Galactus is a giant purple man. that is terifying. it's like, what? a giant purple man is coming thru space and he is gonna eat you. it's a human face that's gonna eat you. haha. to put it dumbly, but it really is way more terrifying than a blob or a tree monster thing. it's truly scary.
he needs to have a face. and be just awe inspiringly huge to be used to his full potential. the human face is what makes it all so weird and good. it's the face that allows us to draw some form and shape to the thing's character. and i think it's important to be able to project this upon him. not like he needs to act like a human, like you said, he barely really says anything or does anything, he just comes, unavoidably. but even seeing act not act like a human, not do much, that translates to us as even more inhuman than something like an amoeba that when you think about it, is the truly more inhuman thing.
when there's an amoeba, you just don't even care what it's thinking. it could be thinking a million things just like we do, but in the context of a story, who cares?
but that's what the tricky part is, becuz it depends entirely on tone, not just of the scenes he's involved in but of everything up to him, whether anyone can pull that off or not. but if anyone does pull that off, they're gonna have a mindblowing movie right there. other ways could work great too, but for me, gimme the giant purple man.
