I rented this movie (or rather my parents rented) from a local video store when I was a kid. It's either late seventies or an eighties movie and all I can remember is rather vague!
There's this child who is being hunted by some mysterious dudes going around in suits, ties and sunglasses - very official looking - could be FBI or similar, not sure why they're after him but I think its because he's an alien! Anyway, this child is befriended by a large bearded man (I think he had a beard) and I think he's some sort of policeman. He's also being menaced by a large group of crazy looking bikers who wear outlandish outfits and are constantly getting their asses kicked by this policeman. I suppose you could kind of call it a cross between ET and Any Which Way But Loose if you can imagine such a thing!!!
I have not dreamt this by the way as my dad can remember renting out the same movie time and time again!
