One Arabian Night) is a 1920 German silent film directed by Ernst Lubitsch based on a pantomime by Friedrich Freksa [de].

[citation needed] In Germany, Sumurun was highly praised by contemporary critics and was described as "a cinematic journey into a universe of emotions and passions of great intensity and utter perfection, with a remarkable Ernst Lubitsch in one of the main roles.

"[2] In America, The New York Times wrote that One Arabian Night (the title under which Sumurun was released) gave added evidence that Ernst Lubitsch "is the superior of most directors anywhere, and that Pola Negri, a Polish-German actress, is one of the few real players of the screen who can make a character live and be something other than an actress playing a part."

[3] The film was released on DVD in the U.S. by Kino Lorber as part of the box set "Lubitsch in Berlin" in 2007 with English intertitles.

It was also released in the UK by Eureka's Masters of Cinema series as part of the box set "Lubitsch in Berlin: Fairy-Tales, Melodramas, and Sex Comedies" in 2010 with German intertitles and English subtitles.
