It depends. If Japan makes a Gundam live action movie, it could work. If America does it, it may have a bigger size budget but I can see causals bitching about how they didn't adapt Gundam Wing instead.

Cause live action anime adaptations are rarely any good

With proper directing and writing it could work. We can make good live action comic book movies. Not to mention most of the bad live action movies of anime and manga are from the west. Japan and Korea has done good live action adaptions better before.

If Japan makes a Japanese live action movie, I do feel like people won't take seriously unless it has good size budget. People will be like "The Gundams look like people in bad suits like the Super Sentai robots!".

I always had this idea if we were going to get a high budget Gundam movie, they'd be able to scan in the 1:1 Gundam statue in Japan as a CG model and make all the mobile suits look in that style.

But I don't get the idea Hollywood could never make a good live action anime movie. Is it just that the people involved don't understand the source material? Is there something inherent in the anime medium that does not transfer to live action well? Because I can't think of anything in the typical Gundam show that couldn't be done in live action with CG.

Japan made Devilman,Cutey Honey,Casharn and AOT so no Japan's adaptions tend to suck too.

Mostly for the same reasons Western ones do.

None of them.

I know that. Most people don't know that those films even existed. People think of movies like Dragon Ball Evolution when news for a live action movie based on anime or manga is being made.

The US could make a good live action movie based on a anime/manga. It took until 1998 to make a good Marvel movie since Captain America (1990), Howard the Duck, Fantastic Four 4 (1994) and Punisher (1989) did suck big time.

With a American Gundam live action movie from Hollywood, we would need a good writer, director and casting to pull it off. Also they would need to show people that Gundam is not another Transformers or Power Rangers type of movie. Casual non geeky people think of Transformers when it comes to giant robots.

Well how hard could it be to find good people in Hollywood? Although Gundam is sci-fi with a complex story, so I'm sure people who specialize in those are a bit harder to find.

But yeah, messaging would be the big thing. They'd defintley would have to distance themselves from PR and Transfromers, and showcase the Gundam very much as warmachines.

Didn't help Pacific Rim.

Man with how poorly G saviour did the chances of Japan outsourcing a live action Gundam movie to westerners is pretty much non existent
