The Marvel star, 37, was aboard a Delta flight to Europe when he shared a hilarious selfie showing all the preventative measures he took for the overseas trip.
The actor was seated on a plane wearing a face mask covering his mouth and nose, an eye mask and a hooded sweatshirt. For extra defense, the actor donned black gloves and had a pillow across his chest and a white blanket wrapped around his shoulders.
"Thanks @delta for getting me to Europe safely...#BuckytakesEurope," the "Captain America: The Winter Soldier" actor captioned the pic, which also shows him holding a glass of white wine.
While it is hard to confirm the actor's identity since nearly every inch of him is covered, fans and fellow celebrities believed he was under there somewhere and communicated mixed reactions.
"Haha OMG," actress Jessica Chastain wrote.
Cara Santana hinted she was "dead" with three coffin emojis.
Another fan joked they "CHOKED ON AIR" while looking at the picture while several agreed, "Safety first."
Dozens of "Captain America" fans made light of the photo by referencing his popular "Captain America" character, Bucky, by responding "Corona bucky" in the comments.
However, some fans said the actor went a little overboard.
"This is..incredibly dramatic," one fan wrote.
Another one of his followers responded: "are you ok?"
"Oh my god SO FRICKING DRAMATIC. Such a drama queen," another fan replied.
"What kind of American clownery is this Sebastian," asked another.
