Who designed attractions such as Pirates of the Caribbean at Disneyland?

The correct choice is Marc Davis, who played a significant role in designing attractions like Pirates of the Caribbean at Disneyland. Davis was a key figure in the development of several iconic Disneyland rides, contributing not just to their visual aesthetics but also to the storytelling elements that are essential to theme park attractions. His ability to blend animation principles with ride design helped create immersive experiences that resonate with guests.

Davis’s approach was informed by his background in animation; he was one of Disney’s famed Nine Old Men and applied his understanding of character design and humor to the theme park environment. This skill set allowed him to create engaging characters and narratives that enhanced the overall experience of attractions, making them memorable and appealing to a wide range of audiences.

Other notable animators and artists mentioned had their own important contributions to Disney's legacy, especially in traditional animation, but Marc Davis was specifically pivotal in the transition of animated storytelling to the physical realm of theme parks, exemplified through his work on attractions such as Pirates of the Caribbean.
