The Co-Optimists is an all-talking sound 1929 British musical film revue directed by Edwin Greenwood and Laddie Cliff and starring Davy Burnaby, Stanley Holloway and Betty Chester.
The Co-Optimists consisted of a troupe of actors and singers and became largely successful by touring seaside resorts throughout England.
In December 1926, co-star Betty Chester appeared in a short film made in the DeForest Phonofilm sound-on-film process, singing the song 'Pig-Tail Alley' from the show.
Hal Erickson of All Movie Guide noted that the revue had recently finished its U.S. run at the time of this film's release.
He stated that the film was poorly received by the critics, although Burnaby as master of ceremonies was praised.
