The film has been retitled Aliens in the Attic. It was formerly know as They Came From Upstairs, but well the new title gets directly to the point and will be more marketable. But with Kung-Fu Grandma starring in the movie, no reason to worry about that:
ALIENS IN THE ATTIC
Action Gaming System
She must be the coolest Grandma ever!
Please keep in mind that it's not a grandma movie: Alien in the Attics is definitely a movie about aliens trying to invade Earth!
