Based on the Marvel Comics series created by Brian K. Vaughan and Adrian Alphona, the upcoming Hulu drama centers on six teenagers who can barely stand each other but must nevertheless unite to defeat a common foe: their parents, whom they discover are secretly members of a group of supervillains called the Pride.

McMahon has been cast as Jonah, described only as "a pivotal player" in the Runaways' fight against their parents.

“We’re incredibly excited to add Julian to our exceptional cast and we can’t wait to see what he brings to the world of Marvel’s Runaways," co-showrunners Josh Schwartz and Stephanie Savage said in a joint statement.
