I have been saying Marvel, or DC I guess, should make a full fledged big budget animated movie for theaters with the bright colors and music and quality animation.
I would say that they should use a character that would NEVER work in a live action movie, because he/she would either seem too unreal, be too expensive, to convoluted a character, stuff like that.
Another thing would be that they are a big a bright character, why waist animation (waist might be too strong a word) on a dark and gritty character that might work in live action. In an animated movie Wolverine's bright yellow costume wouldn't look silly, Luke Cage's yellow shirt and tiara wouldn't look out of place.
(Even though he is DC) Nightwing's original costume with the big collar would be totally fine.
Something else to keep in mind is that this could launch that character into the spotlight, maybe pick a character that isn't well known.
Maybe make an Alpha Flight movie, or a FF movie.
big blue costumes, fighting aliens and all that they do. Space adventures, Dr. Doom, it would be great.
So I guess for now I am saying a Fantastic Four animated movie.
they are well known and bankable enough that the studio wouldn't have to worry about making money. But they are characters that might work best in a full fledged Disney styled animated movie rather than a live action movie.
