What Marvel's New Mutants Look Like In The Comics
4. Cannonball/Sam Guthrie
Somewhere in between Sam's original appearance and his more recent appearance, Cannonball seems to possible have a few changes judging by the teaser.
In The Comics
Sam Guthrie, when we first see him, is seen to be a tall, lanky kid, slightly older than all the other New Mutants. Initially winding up on the opposite side to the team, he winds up a fellow student at Xavier's with the others.
Taking the name Cannonball, Guthrie has the ability to cause a chemical reaction effect letting him blast off like a rocket, or a cannonball. With a field that makes him pretty much indestructible while doing this, he struggled at first with controlling his flight, but became one of the more successful of the students.
He would graduate eventually to X-Man status, and became a much muscular young man and typically had grown out his hair compared to his initial short, cropped cut look.
In The Movie
In the movie, Charlie Heaton plays Sam Guthrie, and he's one of the characters we see a bit more of in the teaser trailer.
He's also one who's perhaps the most unlike his original appearance...with a scruffy, floppy grown out hairstyle, a less physically built physique and loose, laid back clothing. Also, he's gone from blonde to dark hair.
However, those aren't really the most notable differences. As Cannonball is often heard to say in the comics, he's "nigh invulnerable when blasting"...however, in the trailer, Sam has his arm in a sling and bruises on his face. So maybe in the film he's not quite as indestructible.
However, given the amount of scenes in a coal mine, it would seem some of Sam Guthrie's origin story is certainly staying the same, as his powers manifested while working in the mine where his father died. Given the plot of the film is a horror and another character's powers involve peoples greatest fears, it would appear as though Sam Guthrie gets dragged back to this time of his life in the film too.
