“Grand Canyon” [uk] is a great movie from 1991 with Danny Glover (after the 2nd “Lethal Weapon” movie) and Kevin Kline. I originally saw it when it came out and re-watched it today. It is a bit more somber in the middle than I remembered, but ends fairly upbeat. Lawrence Kasdan wrote and directed it. As an aside, he is responsible for the 2nd and 3rd original Star Wars movies having good scripts. For the new ones, George Lucas decided that he could write the scripts himself. And we all know how that turned out.
