Famed film critic Andrew Sarris wrote "Lola Montès (1955) is in my unhumble opinion the greatest film of all time". He introduced the restoration at the New York Film Festival in 2008. He later decided that the greatest film of all time is The Earrings of Madame de... (1953), by the same director Max Ophüls'.
Ophuls surrounded Carol with a solid cast, headed by Anton Walbrook as Ludwig I, Oskar Werner as a student revolutionary and Peter Ustinov as the Ring Master. He shot the film in Germany, Austria and France in three different versions - French, German and English (Ustinov wrote the English-language dialogue). Then he worked with three different editors, each in his own room, on the three different versions.
