The confirmation by Peter Safran solidifies reports from September regarding Thames' involvement in the animated project. During an interview with Collider, Safran spoke enthusiastically about Thames, emphasizing the young actor's deep passion for the character. "Mason always wanted to be Dick Grayson," Safran stated, adding, "He was just obsessed."

This enthusiasm aligns perfectly with DC Studios' broader philosophy of seeking "volunteers and not recruits" for its ambitious new shared universe. Thames, known for roles in hits like How to Train Your Dragon (live-action) and Black Phone 2, brings both talent and genuine fan dedication to the iconic sidekick role. While Dynamic Duo is an animated feature, the approach to Thames' casting is being seen as a template for how DC Studios might select its crucial live-action talent.

This strategy is particularly relevant for the DCU's new Batman, set to debut in The Brave and the Bold. Unlike Robert Pattinson's iteration, who remains in his own cinematic universe, the DCU's Batman will anchor a Bat-Family-centric narrative, focusing initially on Bruce Wayne's relationship with his biological son, Damian Wayne, one of the Robins. Other Bat-Family members are also expected to appear. The emphasis on casting actors who are not only skilled but also deeply invested in the characters they portray is a promising sign for fans hoping for a definitive live-action Dark Knight. This mirrors the casting of David Corenswet as Superman, an actor who had previously expressed his long-held dream of playing Clark Kent. Safran's comments on Thames' casting for Nightwing suggest that the search for the DCU's Batman will prioritize similar levels of passion and commitment, potentially leading to a more authentic and enduring portrayal.
