To anwser the original question:
"how do I get actors to travel?"
Make cool stuff they like and show it.
"How do I make cool stuff they like?"
Use the resources you actually have access to to make something short to show you can tell a little story and that you have the skills to make it.
"How do I make something short?"
- Cut all the 'large' crap like demonstrations where a few 1000 people or villan gangs of 30 persons are involved.
- Put one normal person in an extreme situation, add two people who expect something from in (a boss, a wife, a child, whatever), add an adversary that causes the extreme situation that makes it hard for him to keep everyone happy. (Conflict!)
Make the ending humorous, dark, surreal or absurd.
- Keep it under 5 minutes. You seem to overcomplicate everything, so I guess that also shows in your scripts. Keep it simple!
"But how is that possible?"
Ok, start making something even shorter. Make a commercial for a nonsense product.
Something that will give you 'guts' or 'superpower'.
Now you have an excuse to use a shot of a carchase, a fight, a romantic scene, running through the woods at dusk, etc without a complex scenario. Add a shot of someone drinking or eating or wearing it.
Keep it under 1 minute.
(lol, sounds like a coke zero add... don't try to emulate that: keep it simpler)
"Isn't that a lot of work for less than 1 minute?"
Yes, it is. You may even need a few days (2 or 3) to shoot it all right without rushing or without making it 16 hour days. It will be educational and fun!
Storyboard it well. Plan it well.
Editing should be done in 3 days or less.
"But what to do then?"
Put it on youtube/vimeo, show it to everyone you know.
"But what if it isn't perfect?"
Still show it. Learn from critiques and feedback, but don't let it discourage you, because never forget: you started it and you finished it. A lot of people just talk about it.
You learnt from it, you got more experience and you got something to show.
BTW, it is almost never perfect anyway!
"But what if they still don't want to travel?"
Make something short again with local resources.
It will probably be better than the first one and you will learn even more!
And don't be surprised if there suddenly appear to be more local actors than you thought.
"But that means I made the first one for nothing!"
No, you learnt from it and you can show it: that's not nothing.
Everytime you finish something, you will grow. Grow your skills, grow your portfolio, grow your reputation.
