I haven't seen many of those movies, but my favorite movie was and still is Trading Places (1983).
Eddie Murphy, Dan Ackroyd and Jamie Lee Curtis have created an unforgettable trio in this great movie hit. The main characters are full of opposites. One of them is Louis Winthorpe, who runs the business of a large company that makes a lot of profit. The other is an uneducated tramp Billy Ray Valentine, dissatisfied with his life. What could they have in common? Absolutely nothing. They would never have met if it wasn't for one so-called experiment. I really recommend watching a movie.
