I'm afraid there's nothing listed for this title. Add something here!

Factual error: When driving across the moon, Brad Pitt waves his hand through lunar dust that's floating in the air. But there's no atmosphere on the moon to suspend dust like that, even if was kicked up by another buggy - it would fall straight back down.

Suggested correction: Dust particles become charged by electrostatic and radiated by Ultraviolet rays from the sun. This would cause the dust particles would leap several centimeters above the surface of the moon and the lack of gravity would keep them floating there. This is why the moon has a 'Horizon Glow'.

But these aren't "several centimetres" above the surface - they're a good metre or more up, at head height when sitting in the lunar rover.

There is no lack of gravity at that height. The particles would tend to fall back down to the surface like anything else would. They'd stay suspended at a constant altitude only if there's an upward force to balance the downward force. Even given that much, individual particles would not stay suspended stably owing to dynamics spelled out in Earnshaw's Theorem.

Trivia: The title is Latin and translates to "to the stars". The title credits fade that wording in English into the title.

Question: How did the monkeys get onto the space ship and why were they so aggressive?

Answer: On the way from the Moon to Mars, the Cepheus interplanetary vessel receives an automated distress signal from a Norwegian bio-medical space station (that studies and conducts experiments on Earth animals in the deep-space environment). Apparently, a couple of very powerful and temperamental adult baboons escaped from their cages and killed everyone aboard the space station, feeding on their bodies. When the Cepheus answers the distress signal and arrives at the space station, the baboons attack and try to eat Captain Tanner and Roy McBride, also.
