The adventure series of Indiana Jones needs no introduction, but I'm going to give one anyway because padding (truly, the greatest horror of all)! Indiana Jones was the brainchild of Steven Speilberg and George Lucas before the former stopped denying the stupider ideas of the latter. The first film, Raiders of the Lost Ark, was intended to be a homage to the old pulp adventure serials that the two had watched and enjoyed in their youth. In particular, the iconic look of Indiana Jones was inspired by Humphrey Bogart's outfit in The Treasure of the Sierra Madre, and that and other serials had a heavy influence on the plots of the original trilogy.
But where does The Emperor's Tomb come into play? Well, directly in canon before Temple of Doom, my personal favorite in the franchise. It's 1935 and Indy begins a trek through the jungles of Ceylon to - in the style of Raiders - recover an artifact. After making his way through a ruined temple, matching wits against ivory hunters, and dealing with a great white crocodile, Indiana does indeed manage to recover the artifact...which turns out, unlike the Idol of the Havitos...to be intrinsically important to yet another quest he finds himself on when a Chinese official and his lovely assistant arrive to inform him of - the search for the tomb of China's first sovereign Emperor, Qin Shi Huang. And thus, another epic adventure begins as Indiana travels from New York City to Prague to Istanbul to Hong Kong...and to Hell itself in his quest!
...well, one of them. Chinese got a lot of Hells.
