I've been searching for this movie for years!
I was going to post on the "I need to know" board, but the images were so vague, all I could think to describe the movie was aliens and shaving cream and I for sure thought I was making it up. I'm pretty sure this is the movie I saw as a kid, I remember the cream causing a craze and a little boy. Now can someone tell me if this scene exists, because it would really solidify that it's the same movie for me. The little boy feels pressure to eat the stuff, so he replaces it with shaving cream and eats that instead. I actually have no desire to watch the movie again, but it's been bugging me for years because I always had the image in my mind.
Oh my god, of course this is the movie:
I can't believe it!
