bro4bro saidIf they released Creature from the Black Lagoon in its original 3D format you wouldn't need any special equipment to watch it, just a regular DVD player, a regular TV, and a pair of the cheesy old glasses. But the original 1950s 3D process could only be used for black-and-white movies, and a lot of people claimed it gave them a headache. I'm guessing they won't release that version because they're afraid someone will file suit for pain and suffering.
House of Wax, Dial M for Murder and Kiss Me Kate were all colour 3D movies from the 1950s. They never used the red & blue glasses initially, but polarized 3D:"All of the 1950s US feature-length 3-D films were originally shown by the polarized light method and viewed through gray-lensed polarized glasses, but in the 1970s a few were theatrically re-released as red-and-blue-glasses anaglyph 3-D prints, which, unlike the original format, did not require special projection equipment and a non-depolarizing screen. "
What caused headaches in those days were if the two reels of film required for projection were not synched up correctly and the image had a "ghosting effect":"During its original release, House of Wax used the two-strip Natural Vision 3-D format, which employed separate 35 mm film prints for the left-eye and right-eye images, projected by two separate but interlocked projectors."
All of this is also covered in the Audio Commentary on the blu-ray release of House of Wax.
While they could do a DVD release of Creature with the red and blue glasses, it probably wouldn't look very good. Plus the niche market most likely to buy older 3D titles also likely has modern 3D equipment.
