Jimmy Fallon Made Mark Ruffalo Take An Avengers: Endgame Lie Detector Test

While nobody likes being spoiled, that doesn't stop fans from getting absolutely obsessive when it comes to wondering what is going to happen in their favorite movie franchises. Avengers: Endgame is set to be the biggest Marvel movie yet and Mark Ruffalo is known to be less than perfect at keeping secrets. However, last night Jimmy Fallon took no chances when he decided to hook the Incredible Hulk himself up to a lie detector. The results were... interesting. Check it out in the clip below.

It seems that every time that Mark Ruffalo is on The Tonight Show Starring Jimmy Fallon, the host is ready to grill him for answers one way or another. This time Fallon decided he wanted to have incontrovertible evidence of accuracy. For what it's worth, Fallon does appear to have a legitimate lie detector device on his desk. It certainly looks like the real deal.

Fallon starts by asking if the Hulk is, in fact, a Skrull, a pertinent question coming on the heels of the release of Captain Marvel, which introduced the shape shifting aliens to the MCU. Mark Ruffalo says he can't answer, though the machine claims that he could. Ruffalo also refuses to answer questions about the relationship status of Bruce Banner and Black Widow. He also seemingly reveals that there are secrets in the original trailer that nobody has discovered, by claiming that there are not.

As entertaining as all this is, it was obviously played for comedy and so we can't exactly take any of it to mean anything. It appears the machine was being manipulated for comedic purposes, but even if it wasn't, many of Fallon's questions were asked in such a way that the machine wouldn't read things properly anyway. And does anybody believe Jimmy Fallon actually knows how to hook somebody up to a lie detector?

Mark Ruffalo has been in something of the Marvel doghouse of late, as the guy has a tendency to spill things about the movies, however accidentally. He previously left his phone on and streamed portions of Thor: Ragnarok that he wasn't supposed to. He also actually gave away the emotional ending of Avengers: Infinity War, though luckily his comments only got wide spread play after the fact.

Considering his previous gaffs in the area of spoilers, Mark Ruffalo is probably one of the safer people to put out in public leading into Avengers: Endgame. He's paying that much more attention to every word that he's saying.

All of this took play last night, prior to the release of this morning's brand new trailer. It, like everything else we've seen in the promotions department, tells us remarkably little about what's actually going to happen in Endgame. It also tells us remarkably little about what Mark Ruffalo himself is even going to be doing in the movie.

On the plus side, we have barely more than a month before we'll get all our answers. Avengers: Endgame will be here April 26.
