Thomas Bo Larsen did not receive an Oscar nomination for portraying Theo in The Hunt.
There's one scene that is technically outside of directly interacting with Lucas where it is a tender moment between Theo and his wife. I love the moment because of just how authentic it feels between the two of them and how honestly it just offers a real history outside of the confines. The film excels, amplified by these performances, because it never feels constricted by the central element. That is of course a pivotal factor but as with Bo Larsen's performance there is so much more than that to the community we see, and the people meet that makes the degradation of it all the more powerful. This degradation comes when Klara lies about Lucas's actions, which leads to a sort of hysteria as everyone start to believe it. This isn't simplified which is well shown through Bo Larsen's performance when Lucas comes to attempt to explain things to Theo. Bo Larsen is brilliant as he creates the complexity of Theo's belief because he actually portrays this conflicting feeling, a wish to disbelieve the act of his friend yet the heartbreak of accepting that something horrible was done to his daughter. He manages to make sense of the belief of the lie and actually creates sympathy for the man even though we know he's wrong.
Bo Larsen's work helps to importantly make the situation all the more convincing and honestly are the more heartbreaking. There's a scene later on where Theo speaks with Lucas's son Marcus. Again Bo Larsen finds the nuance of the past within situation as he portrays the underlying desire to reach out as the old friend and help while though offering the cold distress, and tension of man still pained by what he believes has been done to his daughter. This eventually leads to the Christmas Eve Church scene which is the highlight of Mikkelsen's masterful performance. In On the Waterfront one should never dismiss Rod Steiger's contribution to the taxi cab scene most noted for Marlon Brando's performance, nor should one dismiss Phillip Seymour Hoffman's incredible work in the processing scene in The Master though Joaquin Phoenix may leave the strongest impression, and one should not forget Thomas Bo Larsen's contribution in this scene. Bo Larsen's own reactions are essential to the power of the scene as he subtly alludes to Theo coming to grips with a certain shame, and understanding of what he has done to his friend. His final reaction when Lucas stares right at him is particularly effective as Bo Larsen shows that Theo has nothing to say for himself in this realization. This leads soon to an incredibly moving scene where Theo admits his mistake, and this is because Bo Larsen earns this so much as in the sort of spoken realization the years of their friendship and the pain of his mistake is so deeply felt in his face and his words. Thomas Bo Larsen's role overall is limited yet critical to the film. His work not only makes the town's forgiveness of Lucas believable but also very poignant. His screentime is limited but within it he importantly adds so much to the film by granting the needed complexity and really humanity to those who turn on Lucas so brutally.
