Neither 3D story covered IMAX. I remember an innovative 3D IMAX movie that I saw in Chicago about a pilot that was flying mail over the Andes during the early days of flight. It had a fairly major star in the lead (can't remember his name). I don't remember the story catering to the 3D technology but it was very effective. What I liked was the use of both 3D video and 3D audio. The 3D glasses had small speakers near the temples. The film used these speakers for the main characters internal thoughts. Very effective.

This story about the history of 3-D movies failed to cover the writer,director Arch Oboler and his contributions to this field. He also, and more importantly had the most important impact on America through his dramatic, inspirational Radio Plays that depicted the rise of Hitler and Facism at a time when most Radio networks and sponsors kept their mouths shut. Feel free to contact me so i can elaborate.

While discussing the concern that 3-D might distract from the narrative, I was surprised to that "Dial M for Murder". Though it is really seen in the third dimension, Hitchcock did design it to be seen as such.
