Goofy fun!
This falls in the slapstick category. Wallach plays "Black Jack" a hen pecked, straight arrow lawman. He runs afoul of Gemma who plays Blanc de Blanc, a conman, good badman. They somehow get on the trail of a stolen pony who is worth a bundle to the Japanese.
This brings in Milian, who plays a hilarious servant who desires to be a samurai. Bizarre conflics between the three and outlaw types. Milian's accent and behavior, brings real howls to the viewer. The scene of the three of them in drag (Milian's a geisha; Wallach with mustache)is like a Benny Hill\Marx bros. skit. CHECK-IT-OUT!
