The Adventures of Young Indiana Jones: Treasure of the Peacock's Eye

Henry "Indiana" Jones, Jr. (Sean Patrick Flanery) mentions taking part in an archaeological dig in Jerusalem about ten years earlier. This refers to an unmade episode of the third season of The Young Indiana Jones Chronicles (1992), that would have been called "Jerusalem, June 1909", and was supposed to see Indiana's first meeting with his future mentor Abner Ravenwood (who was mentioned in Raiders of the Lost Ark (1981)). Just before this, Indy mentions a different dig in Egypt. This one was depicted in The Adventures of Young Indiana Jones: My First Adventure (2000).

Many of the pirates are armed with M-1 Garand rifles, a weapon that would not be invented until the 1930s.
