Danik, el viajero del tiempo (1996)

Danik, El Viajero Del Tiempo tells the story of an architect dude (Oscar Bonfiglio) who's very irresponsible & extremely cruel. All this dude ever does is drink heavily, smoke heavily, and be cruel to his steady (& pregnant) girlfriend (Maribel Palmer). One night after drinking heavily (as usual), the architect dude is visited by a female alien being from the future. The femalien from the future tells him that 7 years ago she used him to conceive a child and that now is the time for him to meet Danik, their 7 year old martian child. The femalien wants Danik to learn stuff from his 'father' and she wants the 'father' to learn how to be a better person from Danik. So, human father & martian son start out rough at first but then they quickly get along, they start to improve themselves, and Danik uses his powers to entertain the neighborhood children.

Unfortunately the movie Danik, el viajero del tiempo is not yet available on HBO Max.
