I was a kid and saw this film on TV in the 80's.

It starts with a crashed ship somewhere in the desert. There is a man who's an alien but I don't remember the plot... I think he just wants to go home...?

He meets a woman and reveals that he's not from Earth and take off his "disguise", still looking quite human but with strange eyes and no hair...

It is definitely not Starman, it was cheap, made for TV.
