Pegg can thank his innocent, boyish charms for landing his mug in the pages of the comics. The character is actually based on an old friend of Ennis', but when it came time to actually draw Hughie, Robertson initially struggled to capture the balance of determined innocence that the writer described. Then he saw Pegg in the iconic British comedy Spaced, and wee Hughie's look was born.

"Garth emphasized that it was important to capture an innocence but tough determination in Hughie," Robertson told ComicVine. "Two things that seemed to contradict each other and somehow in early sketches he kept looking too old. When I saw Simon Pegg in Spaced I thought he captured that balance perfectly,and Shaun nailed that home."

As a result, Pegg is a dead ringer for Hughie. From the character's close-cropped hair to his average height and expressive face, the Hughie of the comics is instantly recognizable as the famed British actor. By contrast, Quaid is tall and lanky, but much like Pegg, his face exudes a youthful innocence that makes him a great fit for the character, even if he doesn't match up with the comic book depiction of Hughie.
