I saw a movie before, which seems to be American. It's about a rich boy who got into a machine at Christmas and changed his body after coming out. ...

Flying over the future: tells the story of a 12-year-old boy wishing in front of a wishing machine. The next morning, he was surprised to find himself a 35-year-old man. Because of his childlike innocence, he was successfully attracted by a famous toy factory and hired as a research and development position in the toy market without any psychological preparation. He gradually realized the benefits of being an adult-freedom, a lot of money and countless toys. His naive behavior and the new soul of innocence infected many people around him and made them find their lost innocence.
