Vera Cruz was black and white in 1954 but then colorized I think by Turner Broadcasting. Even if it aint the right one, its good.
Vera Cruz was filmed in color. I saw it at the theater in color.
I hear they did a lot,of filming in mexico. so we know the montezuma’s revenge was authentic.
Maybe on your TV it was B/W? It is definitely in color. I have the Blu-ray.
My wife is always saying "I thought that movie was in black and white" because she originally saw so many on TV that way.
