Despite optimistic technologists throughout the 20th century predicting ‘one day all films will be in three dimensions’, 3D is usually a response to periods of crisis in the movie industry. The first spate of 3D was in the 50s when TV was seen (rightly) as the huge threat. We still get revivals of classics form this era, made using the anaglyph system of glasses with one red and one green (or cyan) filter, like Hitchcock’s Dial M For Murder and Jack Arnold’s Creature From The Black Lagoon and They Came From Out Of Space. Anyone who’s seen them probably remembers them for when rocks tumble out of the screen into the audience or when telescopes or scissors loom over the stalls.
