"The Ghost Breakers", a 1940 Bob Hope movie, spoken by Willie Best as 'Alex'.
"THE GHOST BREAKERS, 1940, directed by George Marshall, screenplay by Walter De Leon, from the play by Paul Dickey and Charles W. Goddard. Starring Bob Hope, Paulette Goddard, Richard Carlson, Willie Best, and Anthony Quinn.
Bob Hope stars as a radio broadcaster on the run from the mob who flees to an island off Cuba with heiress Paulette Goddard and his butler/ “family detainer,” played by the unforgettable Willie Best, only to come up against ghosts and zombies galore. Plenty of silliness and lots of Hope’s trademark one-liners, but the most memorable one is spoken by Best, “Feets, don’t fail me now!”
