Richard Harris did not receive an Oscar nomination for portraying Lieutenant Commander Anthony Fallon in Juggernaut.
Now what gets the film truly going is Richard Harris as bomb dismantling expert Fallon. There is perhaps that character that just seems "right" for an actor and this seems to be the one for Harris. There is that role that seems in tune with their onscreen persona, and for Harris here his off screen, or at least, interview persona. This requires a bit of an explanation I suppose though I would just suggest one should go watch Harris in any of his interviews as he is one of the most effortless and entertaining actors in that setting. That charm brings so wonderfully in that setting he transfers here as Fallon, perhaps this was even hoped for by the filmmakers given that they have Fallon being a particularly fond of an alcoholic beverage now and again. Harris to begin with brings such a natural quality to his work with the sheer ease of his performance, and brings a natural levity to the film, despite the severity around his role. Harris is simply naturally entertaining to watch here in a role that he just makes his own in that very special way from the point that in that outset it seems to become quite evident that only Richard Harris could have possibly played this part quite like this.
This is not to say Harris is coasting here, far far from it in fact, in a way it is pretty astonishing how Harris brings himself to the role while fully developing Fallon as his own man. This includes Harris's own bountiful charm for sure, but this is actually part of the character in a two fold way. In part Harris through this shows the confidence of the character that by his charm is wholly endearing, and makes sense out the man who we initially meet as he's casually disarming a far less impressive bomb. Harris though goes further with the idea than just showing Fallon as this expert. There is more in that Harris conveys this lightness in his work often in some of the more intense moments actually. In these scenes Fallon constantly makes humorous side remarks, which Harris does deliver in a genuinely funny way however he goes further with this. Harris in these moments suggests this as partially a defense mechanism of sorts for Fallon in dealing with the situation. This is because Harris never delivers them in a way that seems tonally awkward or ever out of character in the slightest.
Now a reason for that is Harris's overall approach to the part particularly in the bomb disposal scenes which are the highlight of the film, and Harris is a major reason for this. Although Harris projects that confidence so well, along with that humor he doesn't downplay the severity of it in Fallon's mind. In even the moments where he makes his little jokey asides Harris's eyes convey very much the very real concerns for Fallon. Harris is never static here instead his whole performance alludes to a man who has gone through this particular line of work, and has found his way of dealing with. That partially includes his humor, but Harris never simplifies it. I love an early moment where Fallon espouses on his talents in this particular line of work and mutters he wishes he was as such a success in a different line of work. Harris doesn't deliver this line with an overt sadness or anything like this but rather an amused shrug which so well emphasizes the way Fallon has come to terms with this. When Fallon is pressed by the ship's captain (Omar Sharif) on his attitude though we get a bit of a darker side to Fallon, which potentially could've become a confusing aspect to the character, however Harris's firm grasp on the material ensures that it is not.
When something goes wrong or Fallon's methods are questioned Fallon delivers some darker views in regards to the technical insignificant amount of lives in the scheme of the entire universe. These moments much of the time are still with the other members of the bomb squad where Harris still brings a more comedic bent in this philosophy, but with the captain, after Fallon's lost another one of his men, Harris matches the darkness of the message. The callousness though that Harris delivers though comes through an insincerity in attitude in this moment. Harris in part suggests one that he is not terribly impressed by the Captain's concerns, since Fallon is more keenly aware than anyone in regards to the severity of the situation, but it also actually reinforces his personal way of dealing with his particular line of work. Again Harris usually adds that humorous touch to this but in this moment Fallon understandably doesn't bother with easing the words. Harris though shows with that humor and insincerity though the fashioned belief the man uses, not to truly delude himself, but rather to help himself deal with his job where he could die at any moment therefore he needs to be a little insensitive now and again just to be sane in his work.
What we came to the film for though was to see Richard Harris disarm a bomb and we get that in style with Harris. He is down right mesmerizing in these scenes, and he is essential to the film's success since the parts of the film that truly work are the disarmament scenes. Harris again is brilliant in that he layers his performance as noted in bringing a real depth actually to the character's manner during these scenes however he still ratchets the tension up in every moment. Harris is particularly great near the end of the film where the situation becomes more dire and he could be killed at any moment. Harris is fantastic in doing so much tension through his performance by slowly losing some of that comfort in Fallon right down to the final scenes where he loses his humor, and physically Harris reflects the real fear in the situation. Fallon never falls apart, but Harris is great by realizing that he's still a man doing a very dangerous task. My favorite moment of Harris's performance and the film is at the end with naturally one last wire to cut. Harris builds to the moment so effectively, and then releases the tension with his final moment of comfort and perfect delivery of Fallon's very much earned self-congratulatory "Fallon is the champion". I love the line because as much as it is a genuinely, for the lack of a better word, a cool moment for Harris, he also does brings that sense of a sigh of relief along with it. Harris absolutely owns this part from beginning to end creating such a captivating character that steals the film without question.
