I was not aware that only part of Bellboy was in 3D. I watched the rest of it last night and the last reel was well done 3D. My apologies for the misunderstanding. Another fine release from 3D Archives.
We have some projection instruction documents which did not make it onto the disc in time. I was hoping the text on the back cover would have made it clear that the 3-D footage is only the final segment of the film.
I'll scan those projection notes and post on our website.
