Il fiume stanco

The film is part silent, with intertitles, and part sound, which was important to feature the main character's talent as a singer, although the title song Weary River was nevertheless dubbed by a professional singer. One scene near the end features an orchestra playing on-screen on set that is a radio studio, while traditional silent movie sound is substituted for real sound. Then the scene technology audibly changes to sound recorded on film, with the same orchestra appearing to play for real (possibly dubbed) as the main character begins to sing (although he is listed as dubbed) in a radio performance that prompts his sweetheart to call the radio studio. The scene is an unusual mix of technologies during a period of transition from silents to sound.

When Jerry Larrabee is brought in to the prison bathroom, there is already an inmate having a bath, who has disappeared before the scene is over.

First National also released this film in a silent version.
