Factual error: The film informs us the gravity on Neptune's moon Triton is less than 8% of Earth's. But the whole physics of the rocks and his movement on the surface do not reflect that. The actual surface is frozen nitrogen. The difficulty he has in moving around is not well correlated by him only weighing 7kg. Https://www.imdb.com/title/tt5361488/.
