Avengers, Assemble! Paul Rudd, Karen Gillan, Mark Ruffalo, Don Cheadle and Jeremy Renner arrive on set
Cast members of the Avengers movies were glimpsed on Saturday turning up to filming in Fayetteville, Georgia.
Karen Gillan was photographed in full blue prosthetic as Nebula, and Mark Ruffalo was spotted in what appeared to be his motion capture suit to play The Hulk.
Don Cheadle, Jeremy Renner and Paul Rudd were seen at that day's shoot as well.
As Karen, 29, has explained to Den Of Geek, the third and fourth movies in the series - Avengers: Infinity War and Avengers 4 - are being shot in one go.

When she was seen on Saturday, her Nebula costume was a half-sleeved walnut brown top over skintight darker brown trousers and a pair of boots.
Karen began playing Nebula in the Guardians Of The Galaxy movies - multiple characters from which are featuring in these next two Avengers titles.
Don, who plays War Machine in Marvel Cinematic Universe films, was spotted Saturday dressed casually and walking slightly ahead of Karen.
The 52-year-old showed off his toned arms in a pale grey T-shirt worn over dark jeans, and appeared to be checking his phone as he headed on his way.

Jeremy, who plays Hawkeye, had multicolored designs swirling over his left arm.
The 46-year-old hunk modeled a chic pair of sunglasses and skintight black trousers, draping his musclebound torso in a dark grey T-shirt.
Paul pulled of a relaxed style, leaving a couple of buttons of his navy shirt undone over his powder blue T-shirt and folding his sleeves up to the elbow.
The dashing 48-year-old plays Ant-Man in the Marvel Cinematic Universe.
Avengers: Infinity War is due out in American movie theaters next May 4, but it'll be out April 25 in several countries including Australia, and April 27 in Britain.

Karen described the shoot to Den Of Geek: 'It’s been going since January, and it goes right up until December. And then it goes into reshoots - like immediate, more additional photography - next year. So it’s like an ongoing thing, which is really cool, because it feels like a whole family now.'
Among her other upcoming films is Jumanji: Welcome To The Jungle, and she's noted: 'There were a lot of crew members who were on Jumanji who’ve gone onto [Avengers]. So I’m just like: "Okay, this really is my next family."'
This multiple-films-at-a-stretch tactic isn't new in fantasy franchises - Peter Jackson's The Lord Of The Rings trilogy famously had one long, sprawling period of principal photography, followed by a separate stretch of pick-ups for each film.
Another example is the second and third Pirates Of The Caribbean films - subtitled Dead Man's Chest and At World's End, respectively - which were also shot in one go.
