Big (1988) is the classic childhood movie in which a kid goes to a carnival and wishes at one of those creepy animatronic machines to be big. The next day he gets his wish, and finds himself with a 12 year old mentality in the body of Tom Hanks. Now the kid has to grow up fast – he’s got to get a job, and get busy in other senses as well. Elizabeth Perkins plays Susan, the girl who the 12 year old eventually has his first sexual experience with. She and Hanks bounce on the bed together, which, in turn, makes a very visually pleasing part of her anatomy bounce also. A little later on Hanks gets his hands on those bulbs after she strips down to only a bra. Just like the name implied, this was a huge hit in the box office, and still totes one of the sexiest scenes in a kid’s movie.
