If friends who selfie together truly do stay together, then actors Mark Ruffalo and Chris Hemsworth are evidently in it to win it.

On Tuesday, Ruffalo took to Instagram to share an up-close, behind-the-scenes look at the making of his latest film, Thor: Ragnarok, in which he portrays Bruce Banner aka the Hulk.

While the star has shown us what it’s like to transform into the otherworldly creature before, this Instagram features an eye-catching special guest: co-star Chris Hemsworth.

In the shot, Ruffalo poses with Hemsworth, who portrays Thor, inside what appears to be a dressing room complete with coffee cups, hair and makeup essentials, and a fan. “#Thord3 on set behind the scenes,” Ruffalo simply wrote as the caption to the duo’s picture together.

In addition to the above, he also has been using the social media platform to show us what goes on between takes Down Under (filming kicked off last month in Australia), where fellow Thor co-star Tom Hiddleston has also been busy at work. See highlights, including his video from a koala sanctuary, from his posts below.
