That's why the studio goes a bit further with his surroundings on set, including his fancy chair. The Iron Man actor shared a photo of the chairs from Avengers 4, where fans can see normal chairs for Scott Lang (Paul Rudd), Natasha Romanoff (Scarlett Johansson), and Steve Rogers (Chris Evans).
In front of them, however, is a fancier chair for Tony Stark. The chair is lower to the ground (presumably because of preference) and features an Avengers symbol above Stark's name. He shared the photo with the caption "New flick, new short chair. #lumbarsupport #marvel #bts."
While only the chair is visible, Downey Jr.'s trailer is probably just as fancy, at least if previous films are anything to go by. Falcon actor Anthony Mackie revealed how nice Downey Jr.'s trailer is on set in an interview on Live with Kelly and Michael, and it seems everyone's goal is to have lunch in it.
"Oh yeah yeah yeah. So the goal every day is to get invited for lunch with RDJ," Mackie said. "We don't call him Robert, we call him RDJ. So, you know, I'll say this, every day you go to set, you work your hardest up until lunch, right, and then lunch comes and you're like, you want to see who's going to get in that golf cart, and ride past the trailers to Robert's basecamp, and you always try and infiltrate that golf cart. So when the golf cart comes in everybody's outside like "yo, who you picking up?", right? And he then goes to the trailer and he's like Robert would like to invite you to lunch."
Mackie even revealed that the trailer has its own security, though he doesn't envy him.
"And a little dude that stands at the gate all day, sunburnt, just burned. Burned, he's just there all day with SPF 60 ahhhh, Mackie said."
While his impressive basecamp won't be in the film, fans can see Iron Man and Falcon in action when Avengers: Infinity War lands in theaters on May 4, 2018. Avengers 4 hits theaters on May 3, 2019.
