Hello friend!
I want to do an adaptation of a film to Portuguese ...
This is the original:
http://www.youtube.com/v/5WCTltHR-HgI intend to make a similar one using the green screen - or I have to find a real hole!

Could you give me some tips for shooting/filming?
Scenes from the bottom can be filmed anywhere ... but how can I make the scenes where a character appears at the top of the hole and the other fallen there? Or the scenes where you see someone up there? Or the scenes where the camera rises up?
Any idea?
Thanks
