I am looking for the title of a movie I think was from the 80s. All I can remember is that there was a family of tall thin aliens and some kids were trying to help them escape from the government.

Sorry I can't be more specific. Any help is appreciated.

Could possibly be Mac and Me. Mac, the main alien was small ( he was a kid) but I think I remember the parents at the end were tall??

Its mac and me... They put there hands up to there mouth in a v- shape and made a wistling sound. And his parents were extremely tall and lanky.

It is Mac and me. Thanks for your help. I had been looking for tall aliens and had missed this one as Mac the main character was small. I found the attached review of the film which was a good laugh. Thanks again.
