You're right Larry.
I think I can say that it was the most ambitious set undertaken to date (John or Annabelle will correct me if I'm wrong). Although the running time is twenty odd minutes it took a complete day to shoot as there were dozens of relatively short sequences to record and then edit into the seamless production that Annabelle and John have achieved.
Take a look at this image for example. There wasn't time (or space) to set up the green screen and so the result shown was achieved by post edit. I know the plot, but failed to notice that the scene has two Sophias during the initial viewing it flows that well.
I'm very pleased with the result, and those of you watching it will be in for a treat - the four models really worked well together as a team and Annabelle and John have created a real gem IMO.
