To remain unspoiled by the ending of Foxcatcher, avoid the real-life story of chemical fortune heir and fanatical athletics booster John du Pont and the wrestling Schultz brothers. Why fanatical? Well, if somebody has a doctorate in natural science from Villanova and founded the Delaware Museum of Natural History single-handedly but also hangs around with swimmers and wrestlers all the time . . . okay, du Pont could have been some kind of genius polymath, but the film demonstrates why we chose "fanatical."
