Last U.S. mainstream silent movie (many hundreds of silent movies have been made since 1929, but not as mainstream releases by major US studios).
One of the few hit silent productions (although sporting synchronized sound effects) in 1929.
Paramount boss Adolph Zukor vetoed requests by Schoedsack and Cooper to shot the movie with dialog although it did have synchronized sound effects.
Assuming its copyright has not lapsed already, this film and all others produced in 1929 enter the U.S. public domain in 2025.
