16. Indy Is Stalked By A Lookalike - Indiana Jones & The Kingdom Of The Crystal Skull
When Mutt and Indy are attempting to evade KGB agents on a motorcycle, they end up riding onto a college campus and driving into a library. In the shot just before they enter, an Indiana Jones lookalike can be seen at the left of the frame, watching the real Indy (who, in a rare instance, isn't dressed in his signature garb) and Mutt speed into the library while the agents pull up. Though it initially sounds like a reach, looking at the man suggests it must have been intentional: he's got the fedora, the jacket and the same trousers. A weirdly amusing Easter egg, then.
