Fan Casting Red Robin/Theorist (recurring character) in Batman: Under the Red Hood (Live-action adaptation)

By the events of the movie, he has already quit Robin. As the only Robin to not be adopted by Batman, he only ever became Robin to prevent Batman from descending into his grief and thus protect Gotham in the process. Driven to anger by Bruce’s distant mistreatment of Steph (whom he is in love with), the final nail in the coffin happens when he learns about Sheila Haywood and her betrayal that led to Jason Todd’s death at the hands of the Joker. Choosing to quit and help Steph raise her infant daughter with the help of his widowed stepmother Dana Winters, he sometimes operates as Red Robin or as the Crime Alley vigilante Theorist, but mostly stays away from the main story.
