In 1981, Raiders of the Lost Ark came out and introduced audiences to Indiana Jones (Played by Harrison Ford). Now a legendary character in his own right, George Lucas, much like Star Wars, he found inspiration from the most unlikely of sources for Indy and his adventures. The character itself was inspired by James Bond, but even some of the set pieces got some unlikely sources. A fine example is the opening set piece, where Indy discovers a golden idol only to be chased down by a giant rolling boulder. This was actually a conscious homage to Carl Barks' Uncle Scrooge comics,particularly the seventh issue (Published in 1954), in the story "The Seven Cities of Cibola". In this story, Uncle Scrooge finds himself (Along with Donald, Huey, Dewey, and Louie) discovering the lost Seventh City of Cibola and discover a giant idol carved of emerald. The Beagle Boy show up and try to take the statue, setting off a giant boulder that sinks the entire city under rubble. Below is a page/panel from that comic proving this:
This was confirmed by Edward Summer back in 2007 when he put together the Walt Disney's Uncle Scrooge McDuck: His Life and Times collection (Which Lucas himself wrote the introduction for), pointing out Lucas was a big fan of Barks. Almost as a way to "get 'em back", Uncle Scrooge's show DuckTales would end up having their 1990 theatrical film DuckTales the Movie: Treasure of the Lost Lamp using a style and motif very reminiscent of Indiana Jones (While also using a storyline inspired by Aladdin).
