It's widely known that Spielberg purchase the rights to Tintin after a French critic compared _Raiders_to Tintin's comic book adventures. The French critic thought it was a major source despite Spielberg never having heard of Tintin until reading that review.

It took Spielberg dacades to finally produce the film. Now, I think it turned out pretty solid, especially story wise. The overall feel of the film is in fact very Indy-like. Even the music sounds straight out of the former just lacking the Raiders March (I'm mean it is John Williams).

I even dare to say, if they used this screenplay for an Indiana Jones film, it could have turned out to be among the best of the series.
