Grand Canyonscope

Grand Canyonscope is a Donald Duck animated short released in 1954. It was Disney's second cartoon filmed in CinemaScope (following Toot, Whistle, Plunk and Boom), and was produced to accompany Disney's first CinemaScope film 20,000 Leagues Under the Sea.

It is available on The Chronological Donald, Volume Four, as well as an extra on the DVD release of 20,000 Leagues Under the Sea.

Plot
Donald is taking a tour of the Grand Canyon. Although he just wants to enjoy the whole exhibition, this is made all but impossible by constant admonishment from the rulebook-wielding tour guide: none other than Ranger J. Audubon Woodlore. Donald and Woodlore continue to irritate each other - Donald by innocently tripping over various regulations ("Don't drop rocks into the canyon; Don't bother the native Americans; Don't yell at Echo Cliff"; You can't be on the tour without a burro to ride"; et al.), and Woodlore by chastising him for it - until Woodlore himself disturbs a mountain lion...the last one seen in these parts since the Civil War; it is, in fact, the same lion! Woodlore is caught in the middle as said cougar chases Donald through the Canyon, which results in most of it being destroyed (notably, a number of natural rock formations are smashed). With all the other tourists having fled, Woodlore sternly - and rather insultingly - demands that both Donald and the lion dig another Grand Canyon to restore what they ruined; accordingly, he passes them a couple of shovels and yells out "So START DIGGING!!". Feeling extremely remorseful, Donald and the lion agree to do so and they start digging to restore the Grand Canyon back to its former glory while having moping faces.
