John Landis on Road to Morocco

Third in the series of seven self-aware Hope-Crosby Road comedies, this Ishtar-like entry was one of the most popular. Full of Hollywood in-jokes and asides to the audience (much like Warner Bros cartoons), the Road pictures transcend their dated settings with a modernistic approach that has stood the test of time. Famous for an unplanned blooper where a camel spits in Hope's face. The duo's reactions were so funny that the bit was left in the final cut.
