Shout at the Devil is a 1976 action-adventure film directed by Peter R. Hunt and starring Roger Moore, Lee Marvin, and Barbara Parkins. The film is loosely based on the novel of the same name by Wilbur Smith.
The story takes place during World War One and follows the adventures of Sebastian Oldsmith (Roger Moore), an English adventurer who is on a mission to destroy a German battle-cruiser that is awaiting repairs in an inlet just off Zanzibar. He teams up with Flynn O'Flynn (Lee Marvin), an American elephant poacher, and his attractive young daughter, Rosa (Barbara Parkins), to carry out the dangerous mission.
The trio must overcome various obstacles, including hostile African tribes and German soldiers, in order to reach the battle-cruiser and destroy it. Along the way, they encounter a number of colorful characters, including a mystic African leader and a beautiful German spy.
The film is known for its spectacular action sequences, including a thrilling chase through the African bush and a climactic battle between the heroes and the German soldiers. The performances by Moore and Marvin are also notable, with the two actors playing off each other's strengths to create a memorable on-screen partnership.
Shout at the Devil was not a critical success upon its release, but it has gained a cult following over the years due to its exciting action, colorful characters, and unique blend of adventure and comedy.
