I have forgotten the name of an odd planet/sci-fi related movie that was probably released in the 90s or 2000s.
It’s not very popular and consists of a young boy or teenaged boy who is stranded on a new planet with life. There is no oxygen and he must consume oxygen tablet things. He also at one point has to inject medicine into his heart. There are strange monsters/aliens on the planet which he must fight.
I would love to know the name of this movie or to know if anyone else recognises it!
