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. (One joke has J. Audubon Woodlore breaking the fourth wall stating to the tourists in the CinemaScope version, "Uh, spread out, folks, this is CinemaScope." or in the non-CinemaScope version, "Uh, spread out, folks, this is a big canyon.") Additionally, this short marked as the first Donald Duck cartoon to be distributed by Disney's own distribution company, Buena Vista Distribution, instead of RKO Radio Pictures.
