Doughboys (1930 film)

Doughboys is a 1930 American PreCode comedy film starring Buster Keaton. It was Keatons second starring talkie vehicle.

Keaton had creative input in Doughboys, which was partly inspired by his own experience in World War I. Although the writers kept inserting puns and verbal jokes into the script, Keaton insisted that his dialogue, at least, be less jokey. Keaton felt that Doughboys was the best of the films he made for MGM.
