DC Studios has cast Mason Thames as Dick Grayson, one of the Robins at the center of its upcoming animated movie Dynamic Duo. Thames, fresh off the live-action How to Train Your Dragon, lands one of the most recognizable sidekick roles in comics.

IGN reported that DC Studios leadership says the actor is 'obsessed' with the role — the kind of endorsement the studio has leaned on when introducing new faces to legacy characters. Dynamic Duo is built around the Robin mantle itself, with Grayson as one of the Robins the film will follow.

The casting continues DC Studios' pattern of recruiting rising young talent for its rebooted slate, and gives Dynamic Duo its first marquee name. Thames has momentum: the Dragon remake made him one of the year's breakout young leads, and voicing Grayson puts him inside a franchise with decades of built-in audience.

DC has not yet announced the second Robin's casting or a release date for the film, leaving the other half of the duo as the project's next headline.
