Double-Joint

At the beginning of Benjamin Button, the title character is born as a old man baby. He's the same size as a newborn and has the same proportions, he cries and can't speak. Basically a regular baby except he's really wrinkled and supposedly has arthritis and bad hearing and other old age related ailments. Luckily as time goes by he ages backwards, continuing to look physically younger as he should be getting older. Kinda. As a baby he mostly just looks disgusting, then he morphs into an old looking guy who's as big as a kid.

Here's the important thing though, as he's supposedly aging backwards, Benjamin is still growing taller. He has the same size as he should at his age, just has the physical condition of an old dude. So following the logic of his aging process, at the end of his life he should become a giant man-sized embryo. Well I guess he'd need some really big artificial womb to reach that state, but he would have still been a six-foot toddler a couple years before then. Here's a spoiler: that never happens. Once Benjamin gets old/young enough to where he's a teenaged Brad Pitt we loose site of him until he turns into a different, much younger actor. Eventually he just becomes a normal sized baby. I suppose that was a good decision as the movie was nominated for best picture of the year, but I think it would have been amazing to give the audience a less expected ending. Keep the rest of the film the same - a serious story about love and life - but then when it reaches the final act and we see Ben as like a twelve year old who's taller than he should be, everyone would start to think, "Wait, is he gonna end up splitting into a couple basketball sized sperm and egg cells? Nah, they would never do that; this is a love story." Cate Blanchett could try to care for him, but eventually someone would noticed that he's just way too big and take a cell phone pic or something, it would get around the nets, and some government health officials would be like, "We've gotta check this out" and they'd pull up in some armored truck and a bunch of guys in hazmat suits would jump out and pull ben into the back of their vehicle before speeding away. Cate Blanchett could start running after it yelling for them to give her back her Benjamin, then she could do some voice over and say, "That was the last I ever saw of him." Then the screen fades out and cuts to the inside of some lab, Benjamin button as a zygote that looks like something out of a John Carpenter movie in a large tube in the center of the room, surrounded by computers and men in white coats. Roll credits.
