The Gallant Hours is a 1960 American docudrama about William F. Halsey, Jr. and his efforts in fighting against Admiral Isoroku Yamamoto and the Imperial Japanese Navy in the Guadalcanal campaign of World War II.

Robert Montgomery (; born Henry Montgomery Jr.; was an American actor, director, and producer. He began his acting career on the stage, but was soon hired by MGM. Initially assigned roles in comedies, he soon proved he was able to handle dramatic ones, as well. He appeared in a wide variety of roles, such as the weak-willed prisoner Kent in The Big House, the psychotic Danny in Night Must Fall, and Joe, the boxer mistakenly sent to Heaven in Here Comes Mr. Jordan. The last two earned him nominations for the Academy Award for Best Actor.
