Thanks to a few lines of dialog being added to the music/special effects track (similar to Warners' The Jazz Singer (1927)), this was Paramount's first feature with spoken words. The studio's first all-talking feature, Interference (1928), would be released at the end of 1928. Wallace Beery's bawdy song as he walks down the street was shot post-production and became Paramount's first-ever dialogue. Neither director William A. Wellman nor producer David O. Selznick liked the idea.
