Avengers: Infinity War's screenwriter Stephen McFeely said we'll be saying farewell to characters in the film, and early reactions hint at plenty of emotionally stirring moments.

And it wasn't lost on Mark Ruffalo, who said he cried at "three separate occasions" while watching Infinity War. "There was a time when..." he said on Kimmel, getting ready to list the moments when he realized he couldn't drop any spoilers. Dave Bautista also revealed he cried at least one time as well.

Kimmel's batch o' Avengers guests the night prior voted Tom Holland as the "least trustworthy" in the bunch. The host posed the same question to the Infinity War cast who showed up on Tuesday night (Tom Hiddleston, Danai Gurira, Dave Bautista, Ruffalo, and Scarlett Johansson). They all agreed on Ruffalo being the least trustworthy, especially since he accidentally livestreamed the first 15-20 minutes of Thor: Ragnarok on Instagram during the film's premiere.

"In all fairness, it was in my pocket," he said, clarifying that Instagrammers only heard the first bit of the film. "First my phone was just blowing up like I was getting these texts and I was like, I hope my mom is okay." But he couldn't check his phone because it's "rude" and it was his own movie. Luckily, someone from Disney came over to him to tell him to shut off his phone. Crisis semi-averted.

Ruffalo joined the Marvel Cinematic Universe as the Hulk in 2012's The Avengers. Now, six years later, he's set to fight Thanos in Infinity War, arriving April 27. Next, watch Kimmel's guests draw their characters and play a round of "Guess the Avenger":
