The New Mutants Trailer Breakdown: 8 Things You Need To See

6. Charlie Heaton's Cannonball

The next mutant in line for a key part in the film is Cannonball (aka Sam Guthrie), one of the New Mutants' founding members and a second-in-command of their sister group, X-Force (a group also in line for a cinematic feature).

Played by Charlie Heaton in the film, Cannonball is the first to meet Sunspot (who we'll get to in a second), and later finds himself surrounded by some creepy looking coal miners. He's got a broken arm for most of its duration, and later finds himself in the company of a particularly ghoulish fellow with fellow mutant Majik.

In the comics, Guthrie has the ability to generate thermo-chemical energy from his skin, making it so that he can propel himself through the air pretty much like an actual cannonball would. While he - like Wolfsbane - doesn't show off his powers in the trailer, it's unlikely that he'll be de-powered for long. Expect him to take a leading role come its release.
