Elizabeth Olsen, who portrays the unnaturally gifted Scarlet Witch in the Marvel Cinematic Universe, said the upcoming Avengers: Infinity War is "a film of infinite proportions," adding, "it's gonna be big."

Olsen, who was on hand at Disney's D23 Expo for the premiere of the first Infinity War footage, told Yahoo, "I just remember getting emotional, because it was like the history of everything, the ten years of the Marvel universe. And now it's all colliding, and I just thought that was a cool thing to be a part of — something that's been going on for so long."

"It's a lot, it's a lot, it turns on its head quite a bit too, for sure," added Infinity War co-star Jeremy Renner, who will next be seen alongside Olsen in upcoming drama Wind River. "Lots of storylines, lots of characters. It's gonna be exciting. Cant tell you anything, obviously," Renner remarks of the highly secretive Avengers threequel, which will unite nearly every hero of the Marvel Cinematic Universe in a battle against the powerful Thanos (Josh Brolin).

When asked how Scarlet Witch and Hawkeye are going to react upon meeting the Guardians of the Galaxy's Rocket Raccoon (voice of Bradley Cooper), Renner said, "I think it's gonna turn out to be quite a — I can't say these words."

"A sassy bunch?" Olsen suggested. "Yeah, it's gonna be a sassy bunch," Renner teased. "I can't say these words. Sorry, guys. It's gonna be interesting to see if we're in scenes with him. That'd be cool." (Nice save.)

When asked how the relationship between Wanda and Vision (Paul Bettany) will evolve come Infinity War, Renner was quick to answer: "They're in a cabin upstate," he joked, with Olsen adding, "Making robot love."

"I don't know, there are paparazzi photos in Scotland that I think tell enough," Olsen said of the leaked snaps, which (spoiler warning) show Wanda kissing a very human looking Vision.

"Really? I have no idea what's going on," added Renner.

Joe Russo, one half of the Avengers: Infinity War directing team, recently said the third Avengers will, of course, have big stakes:

"You know, with [Captain America: The Winter Soldier] and with [Captain America: Civil War], my brother and I like stakes," Russo said. "We believe in stakes for these movies, we fight for stakes on these films, and I think people should be prepared for a very intense experience in both Avengers 3 and Avengers 4. And they should be prepared for some pretty big surprises."

Olsen and Renner co-star in Avengers: Infinity War alongside Robert Downey, Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Scarlett Johansson, Tom Holland, Paul Bethany, Sebastian Stan, Benedict Cumberbatch, Benedict Wong, Chris Pratt, Zoe Saldana, Karen Gillan, Vin Diesel, Dave Bautista, Bradley Cooper, Pom Klementieff, and Josh Brolin.
