Just watched my Roger Corman Puerto Rico Trio DVD. The best thing about the films are the commentaries - THE LAST WOMAN ON EARTH has Betsy Jones-Moreland and Antony Carbone who star in the film. Roger Corman introduces the film and says in passing that he first thought that he would use lovely Allison Hayes in the title role, but after seeing Betsy in a play in Hollywood offered her the role. He is forgetting, I guess, that Betsy had had a role in his film THE VIKING WOMEN AND THE SEA SERPENT the year before.
Trailers for 11 Corman films + the trailers for the films on the DVD, the scenes filmed a couple of years later so that Allied Artists could peddle the films to tv, and a gallery of lobby cards is also included.
If you're interested in Corman, it's a deal! LAST WOMAN ON EARTH is in color and all the films are in widescreen.
