In 1920, Lang met his future wife, the writer Thea von Harbou. She and Lang co-wrote all of his movies from 1921 through 1933, including "Dr. Mabuse, der Spieler" ("Dr. Mabuse the Gambler"; 1922), which ran for over four hours in two parts in the original version and was the first in the Dr. Mabuse trilogy, the five-hour "" (1924), the dystopian film "Metropolis" (1927), and the science fiction film "Woman in the Moon" (1929). "Metropolis" went far over budget and nearly destroyed UFA, which was bought by right-wing businessman and politician Alfred Hugenberg. It was a financial flop, as were his last silent films "Spies" (1928) and "Woman in the Moon", produced by Lang's own company.
