several scenes. Because of this, much of the material that they performed in I'll Say She Is exists in one form or another. The opening "Theatrical Agency" scene was later filmed for the Paramount Pictures release The House That Shadows Built almost in its entirety. Instead of Gallagher and Shean or Joe Frisco, they impersonate Maurice Chevalier in the filmed performance. The penultimate Napoleon scene was filmed as a cartoon in 1970 by Rankin-Bass in their 30-minute television production The Mad, Mad, Mad Comedians. Groucho, 80 years old, reprised the role of Napoleon. Harpo and Chico had both died by then, while Zeppo declined to return, so Chico's part was performed by Paul Frees, Zeppo was reduced to a single line also voiced by Frees, while Harpo's part, having no spoken lines, was replaced by sound effects. Reportedly, Groucho was impressed by the accuracy of Frees's performance as Chico. The Marx Brothers' last Paramount film, Duck Soup, contains a courtroom scene largely inspired by the one in I'll Say She Is, although there are significant differences. The silverware gag in this scene was recycled for the stage performance of Animal Crackers and is also featured in the film of the same name. This is also the last production by The Marx Brothers in which they were billed under their given names. Harpo was billed as Adolph Arthur, Zeppo as Herbert, Groucho as Julius Henry, and Chico as Leonard. In his autobiography Harpo Speaks (1961), Harpo wrote that theatre critic Alexander Woollcott encouraged the Brothers to use their stage names in any subsequent production, which they did, starting with their next Broadway show, The Cocoanuts (1925), which was later turned into a film version in 1929. Having toiled on the Vaudeville circuit for nearly a quarter century, this would be the last stage performance that The Marx Brothers would perform for Vaudeville theaters. Once I'll Say She Is hit Broadway, they never left. They would have two further Broadway hits, The Cocoanuts and Animal Crackers, which were then filmed in the early years of talking pictures as their first two feature films. With the closing of Animal Crackers, their third and final Broadway show, the Marx Brothers moved to Hollywood, and enjoyed long careers in film and television.
