Dennis Whitaker, M.D. is a fictional character from the HBO Max medical procedural drama series The Pitt , portrayed by Welsh actor Gerran Howell. The character was introduced in "7:00 A.M.", the show's pilot episode, where he begins his first day as a fourth-year medical student in the emergency room of the Pittsburgh Trauma Medical Center. Whitaker is depicted as a determined and empathetic person who initially lacks confidence and experiences several setbacks which make him question his career path, including a recurring joke in the series where he is constantly covered in various bodily fluids. By the second season, he has developed into a more self-assured practitioner and begins mentoring some of the newer members of the department.

Fictional character biography

Season 1

Dennis is originally from Broken Bow, Nebraska where he lived on his family's farm alongside his parents and four siblings before leaving to pursue his dreams in medicine, becoming the first in his family to go to college. He begins his rotation at the emergency room of Pittsburgh Trauma Medical Center, affectionately nicknamed "The Pitt", as a fourth year medical student alongside fellow student Victoria Javadi, and residents Trinity Santos and Mel King, working under the guidance of senior attending Dr. Michael "Robby" Robinavitch, and the other doctors. He initially has a contentious relationship with the cocky and ambitious Santos, who immediately starts referring to him as "Huckleberry" even before learning of his rural background, and teases him for his mild-mannered disposition and lack of confidence. Whitaker has a difficult start to his first day when he is injured when transferring a patient to a bed, crushing his index finger, and gets repeatedly soiled by patients’ bodily fluids. He subsequently loses his first patient, a man named Bennet Milton whom he had connected with, and struggles to accept that there was nothing he could have done to prevent it. Following Bennet's death, Whitaker is reluctant to return to treating patients, but is encouraged by third-year resident Samira Mohan to face his fears. He later joins charge nurse Dana Evans and several of the other nurses with subduing an unhoused patient suffering from drug-induced psychosis that the staff refer to as "The Kraken", and impresses them by showing compassion and treating him humanely, leading him to subsequently volunteer to join a doctor's outreach programme specifically working with the homeless population to ensure the man receives adequate follow-up care. His farm background comes in useful when he successfully catches and kills a rat that was in the department. When there is a mass shooting at a local music festival, Whitaker, King, and Santos are assigned to deal with patients who have extremity wounds. When he is sent to collect more supplies, he finds Robby in the midst of a panic attack and emotional breakdown, but is able to reassure him and convince him to return to the ER by imparting some advice that Robby had told him earlier that morning. At the end of the shift, Whitaker is secretly followed by Santos, who discovers that he is homeless and squatting in an abandoned wing of the hospital. She offers for him to stay in her spare room, which he accepts.

Season 2

Ten months later, Whitaker is now a first-year resident and is still living with Santos. He begins mentoring James Ogilvie and Joy Kwon, The Pitt's new medical students, but clashes with Ogilvie's brash attitude and Kwon's apparent disinterest in caring for patients. When an elderly man is brought in from a nursing home, Whitaker recognizes the man has a POLST in place and advises that all they can do is make him comfortable in his final moments. When he passes away, Whitaker has Joy and Ogilvie remain to observe a moment of silence, while Robby watches with pride.

Development

Casting

Howell's casting as Whitaker was announced on July 12, 2024 alongside the announcement of eight other cast members. [1]

Characterization

Howell feels that Whitaker acts as "the audience's point of view if they can't relate to the very complicated medicine that's going on", and described him as having "the worst day of his life" during the first season, which covers his first shift at The Pitt. He explained that the character's empathy comes from being someone to is "a bit lost in his family" and having to "fight for attention", but feels that he "genuinely cares" about his patients and helping people in need, though Howell also feels that this can sometimes be Whitaker's "downfall" because he can struggle with when to put up boundaries and protect himself in the high-pressure environment of the emergency room. [2] Of his character, Howell stated, "his sort of big obstacle is just his confidence. And the fact everything is so overwhelming, him being from like a small rural community, I think his biggest pitfall is just, it’s just a lot, like, being in a big city and then an emergency department on top of that. But I think there’s obviously real competence there. And…he just has to get past [figuring out] how to how to interact with people in this situation.” On the other hand, “I think his strength is the resilience, that he does bounce back from all of these things…I think he kicks himself, but he keeps going. So, I guess that’s sort of that’s commendable — I hope". [3]

Discussing Whitaker's progression between the first and second seasons, Howell noted the character's increased confidence and idolisation of Robby, explaining that "he's massively influenced by Robby. That first shift was a nightmare for everyone. Robby would never admit it, but I think they see each other. Whitaker is just enamored by Robby and is just following in his footsteps a little bit." Howell considers the scene where Whitaker finds Robby having a panic attack during the first season a moment where the character was able to "step-up" and shows how capable of a doctor he can be, and felt it was a very valuable scene for the two characters and helped to establish a closer working relationship between them. [4] Noah Wyle, who portrays Robby, felt that Whitaker was Robby's "new favorite" by the start of the second season following his fallout with Dr. Langdon in season one, and stated, "to have, you know, our Nebraska farmboy, Whitaker, who was the butt of every joke and on the receiving end of every fluid, become a confident physician in his own right was gratifying to the character." On Whitaker and Robby's relationship, Howell explained that he felt the two men had a "weird trauma bond" because they had seen each other "at their lowest" and that Robby subtly shows this through various ways throughout the series, adding that this also creates an "awkward" dynamic between Whitaker and Langdon. [5]

Howell expressed that he enjoyed seeing Whitaker's improvement as a physician when he began receiving scripts for season two, joking that "there's no way [he] could be this incompetent after ten months", and believed that he had "found his stride", but added that there was a "new experience" to challenge Whitaker by having him mentor the two new medical student. Howell expressed that Whitaker would be reluctant to take on the teaching aspect of working at the hospital because he lacked the confidence to believe he would reach a level where that task would be expected of him. Despite this, he felt Whitaker is "actually quite good at managing personalities when it matters" due to his upbringing with his brothers. [2]

Reception

The character of Whitaker, and Howell's performance, have received a positive critical reception. Ahead of the show's second season, Esquire referred to him as the "not-so-secret weapon of The Pitt", noting how the character is often featured as the "audience's stand-in amidst the chaos of the emergency room". [2] Entertainment Weekly wrote that, "Howell brings his mousy charm to the insecure Dennis Whitaker". [6]

Howell was nominated for the Screen Actors Guild Award for Outstanding Performance by an Ensemble in a Drama Series at the 32nd Actor Awards alongside the rest of the cast. [7]
