fans disliked these changes, Thalberg was vindicated when the film became a solid hit. It helped that the film contained some of what fans consider to be among the brothers' funniest and most memorable routines. These routines were carefully honed in a series of live stage performances, as the brothers took to the road and performed the new material around the country before filming began. However, according to Oscar Levant, the first preview of the finished film in Long Beach was a "disaster", with "hardly a laugh" as was the second. Thalberg and George S. Kaufman spent days in the editing room, adjusting the timing to match the rhythm of a stage performance. About nine minutes was cut from the running time, and the result was a hit. Box office The film grossed a total (domestic and foreign) of $1,815,000: $1,164,000 from the US and Canada and $651,000 elsewhere. It made a profit of $90,000. Opera True to its title, the film includes adaptations of some real opera scenes from I Pagliacci and Il Trovatore, featuring the Miserere duet sung by Kitty Carlisle and Allan Jones. The opera setting also allowed MGM to add big production song numbers (which were one of this studio's specialties), such as the song "Alone", with the departure of the steamship, and the song "Cosi Cosa" with the Italian buffet and dancing. Carlisle and Jones were both trained in operatic singing and provided their own singing voices in the film. Walter Woolf King was a trained baritone, but he portrayed a tenor in the film. His singing was dubbed by Metropolitan Opera tenor Tandy MacKenzie. Subsequent re-editing The film originally was to have begun with each of the Marx Brothers taking turns roaring instead of Leo the Lion (MGM's iconic mascot); Harpo was to have honked his horn. This unique opening was created, but not used in the released film because MGM studio head Louis B. Mayer felt the parody would cheapen the respected trademark. It turned up years later, however, in a re-release trailer for the film. According to MGM's dialogue cutting continuity and Leonard Maltin's audio commentary on the current DVD release, the film originally began (after the opening credits) with the image of a "boat on canal". A superimposed title read, "ITALY – WHERE THEY SING ALL DAY AND GO TO THE OPERA AT NIGHT", and was followed by a musical number
