Warner Bros. has optioned a new movie called The Ditch — but its premise sounds a bit more promising than its title. Written by music-video/documentary producer Sascha Penn (Chapelle's Block Party), The Ditch is about a prison on one of Jupiter's moons, housing the worst of Earth's criminals. A prison guard's family is held hostage and he's coerced into helping a convicted terrorist escape on the terrorist's scheduled execution day. With a good action movie director (and maybe some volcanoes, if they set it on Io) it could be a cracking good actioner. [Variety]
