Hi. I saw this movie in the 90’s, but it’s probably a 70’s or 80’s American science fiction film, in colour. It had a young woman who was an alien, dropped on earth by a space ship. She falls in love with this teenage guy. She has mind-reading abilities, can get into the head of an eagle and see from its perspective etc. She also has this weird 3 legged creature with her, that can kind of stretch all 3 legs and then roll like a wheel at very high speed. Can anyone tell me what this film was?
