Did You Know?


It's mentioned in passing that the spaceship used in the movie is a cycler. A Mars Cycler is a real-life project to reach Mars using mainly gravity assist flybys, originally proposed by astronaut Buzz Aldrin. Once the booster has docked with the cycler there's no way to turn around and go back to Earth since the cycler has very little propellant on board, mostly for minor course corrections. This explains why the captain cannot abort the mission once they discover the stowaway. See more »


All three astronauts have their visors up during the launch. During a real launch, the astronauts' visors would be down and locked the entire time. In an emergency, it's very unlikely they would have enough warning to lower their visors in time. See more »


Marina Barnett: Guys, this is not a call for a solution. The entirety of Hyperion is down there trying to figure this out. I'm only telling you this because I need you to be mentally prepared for what's gonna happen.

In Space No One Can Hear You Not Trying
28 April 2021 | by Mike_O_DwyerSee all my reviews

Somehow an engineer ends up as a unintentional stowaway on a spaceship heading to Mars. How he ends up behind panels screwed in place is anyone's guess (he certainly didn't screw himself in), and not an issue that i remember being answered. Whatever.

At the core of Stowaway is old 'trolley problem': would you sacrifice fewer people to save more? With an extra body on board and a mechanical failure that means oxygen can't be replenished, there are now four bodies using up resources rather than 3. This is something we've seen a gazillion times before in movies, usually as a minor bump in proceedings before carrying on to overcome something with even more at stake. Here, it's the whole premise, which is unfortunate for something that was dealt with in 5 minutes in The Good Place.

The main problem is that the noble idea of sacrifice for the greater good has no dramatic weight unless the characters involved are likeable. Toni Collette is well on the road to becoming a national treasure, it's almost impossible not to like her. Unfortunately, everyone else is expendable. Daniel Dae Kim is upset about his plants, which...meh. Shamier Anderson, the accidental stowaway, is injured and has a sister back on earth he's the guardian of which means meh. Anna Kendrick's soul is pure meh.

Between the plants and the oxygen and the go outside and fix the thingy bit, what we have is the middle bit of Danny Boyle's 'Sunshine' with a made for TV script and no budget for character development.
