In the London revival, there is a sound effect of the helicopter timed with the projection to make it appear as though it flies quickly overhead and then off into the distance (similar to the 2003 tour). The sound then queues the return of the helicopter as a set piece (like the original production). I thought it was effective. To me, this revival had moments that were inferior to the original, but also moments that were better than the original. I enjoyed it much more that I thought I would and my boyfriend, having never seen the show before, was really wowed by it, especially the nightmare sequence.
