You have to watch this awesome pitch for a really cool sci-fi film idea called Chrononaut. The video comes from Zach Lipovsky who has also written a feature length script for the film. This has the potential to be something pretty spectacular. The pitch trailer definitely sold me on the idea. Here's the short synopsis that comes along with the video:

A dead mother’s will instructs the estranged father and daughter to spread her ashes in a remote cave. Trapped inside, they find a futuristic safe house and a time machine capable of bringing her back. They must learn to work together to fight threats from their future and escape the cave alive.

I think it would be great to see this project get picked up and developed into a feature film! Thanks to Firstshowing for the heads up on this.
