Limitless (2015)

The television series "Limitless" does not feature any identifiable LGBTQ+ characters or themes within its narrative. The show primarily focuses on its main protagonist, Brian Finch, and his interactions with the FBI and the NZT drug, without exploring queer identities or storylines.

The show features female characters in action roles, such as FBI Agent Rebecca Harris and the skilled Piper Baird. While these characters engage in confrontations with male opponents, their victories are typically achieved through the use of firearms, tactical maneuvers, or intelligence, rather than direct close-quarters physical combat utilizing martial arts or hand-to-hand skill.

The show "Limitless" is a sequel to the 2011 film, introducing new main characters while retaining the established gender of returning characters from the film. No characters canonically established in the source material are portrayed with a different gender.

The show 'Limitless' (2015) primarily features new characters not present in the original film or novel. The returning character, Eddie Morra, is portrayed by the same actor (Bradley Cooper). No established characters from prior canon were recast with actors of a different race.
