I want to ask about a film.. two men fell on earth who were not human... they are enemies of each other.. when they injured they can fix their wounds... young man met a girl who is brunette and she helped him... They had sex in the shower.. etc...

I would like to know that too, I remember it hd russel crowe as one of the aliens in question. And they had blue blood

Actually I think I'm confusing this movie with virtuosity, sorry

I found it I guess Not Of This Earth (1995)
