Me supongo que incluirán más o menos lo mismo que ya venía como material adicional en el LaserDisc, y luego en el dvd:
The extras on this disc center on the famous unreleased roadshow version. In the early 90s, Image and MGM released a laserdisc that had the two major missing scenes, but only parts of them: The Curious Case of the Upside-Down Room, a comic attempt by Watson to cheer up his bored friend, was audio-only; and The Dreadful Business of the Naked Honeymooners, where Watson takes a turn at playing detective, was picture-only. The laser played an interview over the audio track of one, while subtitling the other.
There were other alterations for which no film survived. The lost opening had Watson's grandson claiming the box of precious artifacts left in charge of bank manager John Williams. A key flashback on the train to Inverness told the story of the collegiate Sherlock's encounter with a dream-girl sweetheart - who turned out to be a prostitute and warped his perception of women forever. These were barely covered on the laser, but the DVD uses script excerpts and some newly-found stills from the AMPAS ... although photos for the prostitute scene are still very thin.
¡Ojalá hubieran encontrado todo lo que se amputó!
