As far as glow-ups go, this is one for the ages.

Remember that awkward teen from the movie We're the Millers? You know, the one who got bitten by a spider and flashed his swollen genitalia to Jennifer Aniston?

British actor William Poulter, now 28, rose to mainstream prominence in the 2013 comedy film alongside Aniston, Jason Sudeikis and Emma Roberts.

The then 19-year-old was recognised for his distinct mannerisms and eccentric comedy skills, before going on to star in The Maze Runner and The Revenant.

Fast forward a few years and Poulter has been cast as superhero Adam Warlock in the Marvel Cinematic Universe, and is set to appear in the upcoming Guardians of the Galaxy Vol. 3 in 2023.

Now, given you probably best remember him as the awkward teen with swollen balls, you may not have picked Poulter among the Chris Hemsworth-variety of star.
