Enemy Mine is a science fiction film not set within the Solar System which was released in 1985 and is directed by Wolfgang Petersen.
Humans and Draks are at war over planet possession. When a Human and a Drak are both marooned on a rocky planet, they must put their differences aside to survive. They don`t exactly get on well at first but come round to liking one another. Shigan has only one gender and so can self-replicate and when he gives birth, Davidge has to take care of the new born called Zammis. The human acts as a surrogate father to the young Drak. When slavers arrive on the planet, Zammis is kidnapped and so Davidge launches a rescue bid. After rescuing Zammis and other Draks, he is taken to the Drak home world and is rewarded. This starts the ending of the war between the two planets.
