These 4K 60fps upgrades, increasingly common over the last couple of years, vary in quality. This assortment of clips of 1927 Berlin is one of the better ones. A capturing of the actual world of Cabaret, which was based on Christopher Isherwood‘s “Goodbye to Berlin“, about his time in Weimar-era Berlin (1929–1933). I’ve visited this storied city three or four times — I’d go there again in a nanosecond.
