Os Rapazes Felizes

The animated credits begin with the names and faces of Charles Chaplin, Harold Lloyd and Buster Keaton, followed on the next title by the text "do not participate in this film". The letters are then mixed and reappear as "in this film participate", followed by the actual cast members. The credits also list "Marya Ivanovna" with a large question mark; the question mark turns into a cow, which then paints with her tail the title of the film (in the film, Marya Ivanovna happens to be the name of a lazy cow in the herd tended by the main character Kostya Potekhin).

In 1958, director Grigoriy Aleksandrov made a re-dubbed version, pretending that the original soundtrack had been damaged. Leonid Utyosov's lines and songs were dubbed by Vladimir Troshin and a few lines and scenes were deleted because of censorship. The animated title credits were remade with some changes: for example, the words "Jazz comedy" above the main title of the film were removed; the animated cow was no more spitting as in the 1934 original.
