Mr. Hook is the title character of a series of American animated cartoon shorts produced between 1943 and 1945 during World War II for the US Navy. The series included for 4 shorts with the first by Walter Lantz Productions being produced in full color and the remaining three produced by Warner Bros. Cartoons in black and white. The character was designed by Hank Ketcham. Unlike the earlier Private Snafu series, which was created as an instructional film series, Mr. Hook was created exclusively as propaganda to encourage Navy personnel to purchase war bonds.

Directed by Chuck Jones, Mr. Hook is woken up while a little angel and devil of himself argue whether he should spend or save his war bonds before he returns home. The angel soon wins the argument and tells Hook to save his bonds until he climbs back into civvies.
