WATCH: Fans may have decoded Mark Ruffalo’s bleeped out Avengers 4 title

The title alone is a massive spoiler! (Provided it actually is the title.)

For while now, one of the biggest secrets on one of 2019's biggest movies is the actual name of the movie. So far, we've been calling it either Avengers 4, or Infinity War 2, but the folks at Marvel and Disney have been keeping a tight lid on it, apparently because they figured the title itself would be a bit of a spoiler. And if what Mark Ruffalo said on The Tonight Show with Jimmy Fallon is actually true, then they were absolutely right. In the last few weeks and months, we've been compiling every bit of rumour we could get our hands on, and now Ruffalo may have given us our biggest piece yet. When teased about revealing the title of the movie by Fallon, the big-screen Hulk was actually bleeped out: Clip via The Tonight Show Starring Jimmy Fallon He also jokingly went on to reveal the whole end of the movie, which we are all taking a little less seriously. However, revealing a fake title wouldn't be much of a funny joke, and many folk on Twitter were quick to use some spiffy software to break down what Ruffalo actually said the title of the movie was: https://twitter.com/antovolk/status/1048873100199284736 So it looks like, and sounds like, Ruffalo referred to the next movie as The Last Avenger. Which... could mean one of three things here: (1) There will be only one Avenger left standing at the end of their round two with Thanos, which could link back to our time-travel to rewrite history theory. (2) That the arrival of Captain Marvel will be the last addition to the Avengers, making her the titular Last Avenger. (3) Ruffalo is f*cking with us. Thankfully, we only have to wait until 26 April 2019 to find out...
