Remember going to see this in Leicester Square on an afternoon off, when it first came out. Just wanted to see a movie but had no idea what. Chose to see this film but had no idea what it was about, but because it had a small picture on the poster, of I think, a rocket taking off,(in the background) I thought it was going to be a space set sci-fi film like Star Wars. So sat all the way through the film, I was expecting and waiting for the rocket launch and space fighting bit! As a result, I came out of the film a bit disappointed!
It is only when I watched it again a few months later, that I thought it was excellent and remains incredibly relevant with great set and fashion design etc (retro futuristic?!) . A classic!
I always try to avoid trailers for films nowadays as they seem to show most of the main parts, so you feel as if you have seen most of it already, (no surprise and delight) and I think it mostly best to approach a film when you don't know what to expect. But this was one case where it would have been better if I had at least read a short synopsis beforehand!
