Virtual Reality (with HMDs) breaks the fourth wall. Rather than looking at the movie, viewers can be in the movie/game/play/documentary . With respect to the subject of space environmentalism and the challenges (see above) of making people care/ engage with the subject this may be useful.
Pros
Cons

Physical interactive storytelling experiences have proven extremely successful vehicles for storytelling. Presence is very real and immediately achieved

Cons
examples:
