David Harbour is a sturdily built man, who stands at 6'3,” and although he comes off as a teddy bear offscreen, he is most certainly a man you would not want to tangle with.

When Harbour showed up on set for the 2020 action film “Extraction,” however, he got an education in the mind-blowing massiveness of his Australian co-star Chris Hemsworth.

Hemsworth is also 6'3” and, as the Marvel Cinematic Universe's Thor, looks like he could shot-put your average human being into the sun.

Harbour was in awe of Hemsworth's might and size, telling Pinkvilla, “It's crazy! He's so physically large. Like, I'm a big guy. [...] I'm not used to people being bigger than me.”

He added, “There was one point in the thing where he's supposed to lean against me, and I just hit him, and I'm supposed to move him this way [*does a hand gesture*] real quick.”

Harbour concluded, “I remember I tried to do it once, and it was like an ox, it was like trying to move a stone wall. That was like, he's just so big! That's why I couldn't.”
