Silencio (SF movie trailer).

Here’s the trailer for the science fiction movie, Silencio, in which a couple of scientists – played by John Noble and Rupert Graves – find a resource which allows them to travel a little way back in time and change the time-line.

They use it to alter events save one of their family’s from a car crash, but then some bad dudes cotton on to the advantages of using it for evil.
