In the in-Bulgaria section of the book, it mentions a Czech film called "Lemonade Joe". I found the file online at easterneuropeanmovies.com/lemonade-joe/ (not free to watch, but a 24-hour membership is reasonably cheap). It's weird and delightful - in parts a loving satire of the Western genre (think Blazing Saddles or The Three Amigos but a decade or two earlier), in parts a slightly clunky but on-point critique of product placement / sponsorship culture, and in parts just fun slapstick comedy. Plot definitely drags in the middle, and there's a blackface scene (as unconvincing disguise, not minstrelry at least) that has aged very poorly, but worth a watch.
