(I am aware of this question, but the question didn't word its request properly and as a result didn't get the desired answer)
In Iron Man (2008), a common shot is used to let Robert Downey Jr. act while Tony Stark is in the suit. This one:
Unlike many HUD shots, this isn't a POV shot looking at his viewpoint. It takes some liberty with reality to achieve its purpose in a unique and effective way.
Did Iron Man pioneer this technique, or are there other films that previously used the effect?
- The camera must be "in" the helmet. Close-ups of a character's face while they're wearing a helmet or mask don't count.
- By extension, the shot should be "impossible". If there's room inside the helmet for a camera (somehow), it doesn't count. Technically, interior shots in Pacific Rim are shots from "inside" a "helmet", but the helmet is so big the effect isn't the same.
