The discovery of life on Mars is the beginning of one astronaut's nightmare in the first international trailer for The Last Days on Mars. Liev Schreiber stars as Vincent, who goes out alone in search of life on the red planet, when he realizes that something horrifying is hunting the rest of his team. Take a look at the latest footage from director Ruairi Robinson's sci-fi thriller, debuting on VOD formats October 31 before heading into theaters December 6.

On the last day of the first manned mission to Mars, a crew member of Tantalus Base believes he has made an astounding discovery - fossilized evidence of bacterial life. Unwilling to let the relief crew claim all the glory, he disobeys orders to pack up and goes out on an unauthorized expedition to collect further samples. But a routine excavation turns to disaster when the porous ground collapses, and he falls into a deep crevice and near certain death. His devastated colleagues attempt to recover his body. However, when another vanishes they start to suspect that the life-form they have discovered is not yet dead. As the group begins to fall apart it seems their only hope is the imminent arrival of the relief ship Aurora.
