Jimmy Fallon Just Forced Mark Ruffalo To Take A Lie Detector Test In An Attempt To Get Some 'Avengers' Spoilers

As the premiere date of Avengers: Endgame creeps closer, fans are taking more extreme measures with every passing day to find out what exactly happens in the new film.

Jimmy Fallon, host of The Tonight Show, is no exception, though there's one significant different between him and the average Marvel fan: he has personal access to Mark Ruffalo.

When Ruffalo, who plays the Incredible Hulk, appeared on The Tonight Show to promote the new movie, Jimmy wasn't going to pass up his chance for a few Avengers spoilers, secured through any means necessary.

He did what any diehard fan would do and hooked Ruffalo up to a lie detector to ask him some questions.
