At the recent San Diego Comic-Con panel for the ABC series The Rookie, star Nathan Fillion responded to fan questions regarding possible guest stars on the show. During the discussion, the possibility of Neil Patrick Harris joining the series as a villain was raised, capturing the interest of the cast and fans alike. Fillion expressed enthusiasm about bringing Harris on board, joking that Harris owes him, which could help make the guest role a reality.
The History of Collaboration Between Nathan Fillion and Neil Patrick Harris
Nathan Fillion and Neil Patrick Harris have shared the screen before, although not in similar roles to those seen on The Rookie. Their first notable collaboration was in the web series Dr. Horrible’s Sing-Along Blog, where Harris played the ambitious supervillain Dr. Horrible, and Fillion portrayed his egotistical nemesis, Captain Hammer. This cult favorite series gained viral popularity for its innovative take on hero–villain dynamics.
The duo later appeared in Netflix’s adaptation of A Series of Unfortunate Events. Harris took on the role of the sinister Count Olaf, relentlessly pursuing the fortune of three orphaned siblings, while Fillion played Jacques Snicket, a member of the Volunteer Fire Department who tries to protect the orphans. These roles solidified a pattern of Harris as the antagonist opposite Fillion’s characters.
The Rookie itself continues to flourish as a police procedural drama based on the real-life experiences of LAPD officer William Norcross, recently securing a season 8 renewal scheduled to air in early 2026.
The Recurring Dynamic of Harris as Villain to Fillion’s Hero on Screen
The professional relationship between Harris and Fillion has consistently featured Harris in villainous roles counteracting Fillion’s hero characters. Despite their real-life friendship, the two actors have portrayed adversaries in all their collaborations. Harris is known for his comedic role as Barney Stinson on How I Met Your Mother, but his villainous performances showcase a different side, such as the insecure and greedy Count Olaf or the attention-seeking Dr. Horrible.
Fillion, often cast as charismatic, rogueish heroes in shows like Firefly and Castle, adopts varying character traits when paired with Harris. For example, as Jacques Snicket, Fillion’s character displays a straight-arrow persona, differing from his typical charm and swagger. Meanwhile, Captain Hammer’s arrogance contrasts with Fillion’s other roles, highlighting the versatility of their on-screen rivalry.
This established pattern of their confrontations contributes to the heightened tension and unique chemistry fans have come to appreciate. Should Harris appear as a villain on The Rookie, it would represent a continuation and evolution of their intriguing artistic dynamic.
Significance and Anticipation Surrounding Harris’s Possible Role on The Rookie
Neil Patrick Harris has expressed interest in revisiting villainous roles in the past, notably wishing for a Dr. Horrible sequel, though it seems unlikely now. Taking on a villainous character in The Rookie would allow him to explore that creative interest in a new setting. For Nathan Fillion and showrunner Alexi Hawley, securing Harris as a guest star would add notable excitement to the series and please long-time followers of both actors.
Fans who have followed their work together can anticipate a compelling continuation of their on-screen rivalry, blending Harris’s flair for complex antagonists with Fillion’s grounded heroic presence. The potential collaboration holds promise for intriguing storylines and heightened suspense during the upcoming season of The Rookie.
