I just wrote a lengthy reply and lost it. So I am going to summarize the points I shared. And I'm happy to address them at length later with you. I think you have workable play as long as you are willing to make additions and changes to keep the message and essential integritry in place.
First, I would integrate the three situations so they can be seen happening in parallel. One way to do that would be to take the fathers from situations one and two and make them characters in situation three--guard(s) and/or prisoner. Realize you will need to add more characters as support. Don't tell the story of the robbery, you will show it acted out, for example.
Second, create a visual anchor that starts each loop through the situation. It indicates the event is starting all over again. Go from your worst endings to your best endings. People like positive resolutions in movies.
Third, you need a way of explaining to a visual audience why the scene is repeating. In science fiction, time travel always works. However, you may want to use a different approach.
One way you could handle it is to have three men travelling in a train reading a paper. One comments on a story he's reading saying "This is what I heard". Slip into your worst case. Then flash back and a second man, "That's not what I heard. It went like this." Slip into your second case. Finally a man whose face is blocked states "You gentlemen are both wrong. What really happened was this." Your third and final positive situation. Train whistle blows, conductor announces the name of the town, and the stranger (one of your main characters) arises and exits. (Probably Father One returning to his wife and ill son).
I think your play will work but you need to make changes. The visual media will allow you to overcome some of the structural limitations a fixed stage imposes.[/QUOTE
Thank you for your precise, dedicated and canny answer! You sound like you have read the play, already! It is interesting proposal two fathers to be guards, but I am scaring that I will loose CLAUSTROPHOBIA that exist in all three situation. Integrity of one space and all those hidden conflicts. But I will seriously think about it.
About, a visual anchor... In the play I have three songs separating three parts. So, yes, I will have something new here... Something very recognizable...
"Go from your worst endings to your best endings" - that is already there
And, YES, there must be something that will unite all three stories. Maybe train, or something from inside of a story.
I think that I missed something in the short synopsis, and you detected it. All stories are mostly complement to each other. BUT They are not matching completely. Yes, THANKS!
