Most of the story is presented in conventional blackandwhite. However, whenever Dr. Barnes is about to put on the mask, Barnes voice urges the viewer to, Put the mask on, NOW This was the cue for theatregoers to don the 3D glasses originally shaped like masks which they were given upon entering the theatre. The terrifying visions experienced by Dr. Barnes were then presented in anaglyphic 3D.The 3D sequences, three in all, last 14.65 minutes 879s. They were designed by montage expert Slavko Vorkapich, and feature an array of distinctively psychedelic visuals, some of which are mildly gruesome.
