I saw a movie ages ago. It was like ET but there was a boy in a wheelchair that moved to a new town, he meets the alien because he rolls down a big hill and the alien stops him. The boy dresses the alien in a bear suit. I think it drinks heaps of pepsi too. It also whistles to cantact its family(it think) and its family live near big white windmills... I would really like to know the title because it's a wicked movie, any help would be greatly appreciated!! :)

Sounds Like "Mac and Me" (http://www.imdb.com/title/tt0095560/) (1988) The aliens drank Coke to live. The movie contained a lot of product placement.
