Dupont, written by Arnold Bennett and starring Gilda Gray, Anna May Wong, and Jameson Thomas.

The film was shot on location in London,[2] produced by British International Pictures.

This version included a music score and sound effects by Harry Gordon, along with a five-minute sound prologue titled "Prologue to Piccadilly" that was added to the beginning of the film, featuring just two actors: Jameson Thomas who plays Valentine Wilmot in the film and John Longden as the man from China.

The part-talkie was the version that was exhibited in the United States, released by Sono Art-World Wide Pictures in July 1929.

Valentine Wilmot's Piccadilly Circus, a nightclub and restaurant in London, is a great success due to his star attraction: dancing partners Mabel and Vic.

One night, a dissatisfied diner disrupts Mabel's solo with his loud complaints about a dirty plate.

When Mabel reaches into her purse for a handkerchief, Shosho sees a pistol inside and grabs a dagger used as a wall decoration.

In his 15 July 1929 review for The New York Times, Mordaunt Hall observed: "Perhaps the greatest asset of Piccadilly comes from the camera.

[4] Rotten Tomatoes rates the film 79% fresh, based on 24 contemporary and modern reviews.

Naturally, Piccadilly's publicity made much of Wong's exotic beauty: one contemporary poster—for the film's Austrian release—carries an illustration of the star dancing topless.

It would have been unthinkable to portray a white actress in this way and, needless to say, no such image appears in the film.

The DVD distributor decided to remove the original soundtrack as the sound version of Piccadilly is not in the public domain as it was copyrighted by Sono Art-World Wide Pictures but never renewed.
