What is the first movie you remember seeing this in?
The first time I was awed by that effect was in Stanley Kubrick’s The Shining (1980); see at youtube. Trust me, on the big screen, you felt like you were flying. Had it been done as impressively before?
My earliest memory of the effect was in one of the few Cinerama features I saw in the early 60’s. Can’t remember the title, but it was mostly a collection of things that had the Gee-Whiz effect of making you feel part of things like plane rides, roller coasters, stuff like that.
It might have been as prosaic a title as “This is Cinerama.”
Because it was awesome. Best second of the movie. It’s at the end, with a voiceover saying soemthing about how we struggle to have control over our lives (shot of front wheel of bike from rider’s POV)… or the manner of our deaths (CLIFF!).
