THAT'S IT ! It's the fantastic journey, I straight away remembered it when I saw the picture of the cast. Yeah i actually do remember a big silver what i thought was a car in the film, i guess it must of been a time portal instead. (it sure looked like a car, it had wheels, doors and all !)
It seems the Roddy McDowell thing clinched it
i don't know why i remembered him, but he did leave an impression.....i guess he did his job well !
No I don't remember watching Logans run, although I do remember the title for some reason.
Thanks guys for your help, this thing has been niggling away at me on and off for a few years, I've just never got around to chasing it up.
