Well, I've been theorizing that the whole Indiana Jones series as a whole was a reaction to Spielberg's alleged love of Lupin.
Edit: It's also totally different from his style, but Koike's favorite Lupin appears to be Cagliostro.
Well Spielberg has allegedly only seen the car chase sequence from the beginning of the movie; hence the tagline on both the Streamline and the Manga Ent DVD releases.
And George Lucas came up with the idea for Indiana Jones based off corny adventure serials just like Star Wars was.
Raiders and Cagliostro are only 2 years apart. The early subbed premiere of Cagliostro in Los Angeles was slightly later in mid 1980 or so. Raiders came out in 1981. So I'm not sure if Spielberg would have built that much of Indiana off of one movie.
But, as I've mentioned before, there are shots in both Cagliostro and Temple of Doom where somebody gets crushed by a piece of machinery. The Goonies has a scene where Data falls down a trap door and catches himself by grappling to the ceiling with something that shoots from his belt. And The Last Crusade has Indiana Jones infiltrating a castle while in disguise and then climbing to the roof to break in through a window to rescue someone (his father of course).
So I'm not sure when or how he saw the film, or if he's seen any other Lupin title; but there is evidence to suggest that either he saw it, or someone on his story team did. But I don't think it was an intentional agenda through the whole trilogy, though.
