The moment from Costner informally perusing the paperwork to find out about this case to the realization that it is her, is neither completely sublte , nor completely overt, it's simply frighteningly authentic. The unconscious reaction that would allow him to be discovered if the party in the room, (Hackman's Brice and his loyal lieutenant Scott Pritchard ) were at all aware of, or even suspicious of the possibility it might be Farrell is the obstacle here. The then conscious action to try and be covert, to repress even for a moment the well of feelings that would crest at the top of ones throat like a tidal wave if one were to make such a grsily discovery of a loved one - is frankly a masterclass in acting. Costner imagines it and he goes for it, and what he delivers feels real. The averted eyes darting back and forth as he tussles back and forth between emotions is an incarnation of the dueling emotions present when Brad Pitt yells out “No!” in the finale of “Seven”. You can hear Costner' s eyes in conversation with his conscious. Some version of " No it can't be...I can't.. not here...Wait I can't...how.??...I'm going to be sick". The subsequent bathroom scene is like slow leaking the air pressure out of a tire, or a shaken bottle of soda, at any moment he could explode and the contents would then be everywhere and for everyone to see. No moment, from his realization, to his visit to the bathroom for some release - is made for the audience to join. We can identify with either of these men, Ray Miland's George Stroud, or Kevin Costner's Commander Farrell in scene, but the constitution, construction and purpose of one ( The Big Clock ) is specifically tailored to ask us to join in and say “What should he do?”. The other (No Way Out) simply asks what could you even do? Costner gives us a version, and again space plays a role. After finding out he has nowhere to go, he’s looking for some space some place away where he can let out what has to be let out. Reading Costner's expression its as if he feels he's already starting to seep emotion. He excuses himself to a bathroom and finding not enough space for his emotions there, curls himself into a ball. Making himself smaller and smaller he begins looking into walls, on floors, for anywhere to scream into, desperate to just let go. It's brilliant acting. Intuitive, less about the explicit than the implicit, and more about what's going on inside than the external factors that inform Millands eqaully unpredictable, but more calculated reaction. Beyond the protagonist, and still integral to the plot there are the performances and characters of Charles Laughton and Gene Hackman as the "Framers" Janoth and Brice. Janoth is the head of a news magazine behemoth, powerful , influential, and drunk with both. Brice is Defense secretary, he is powerful, ( though maybe not as powerful, or influential as Janoth) and he is also much more visibly insecure. His right hand man Scott Pritchard (Will Patton) is less the straight man “cleaner” that George Macready's Steve Hagen is , and more an obsessive caretaker. Brice's (Hackman) power resides mostly in the building he works in, Janoth's extends quite a bit further. Charles Laughton like most of his counterparts in the film is bigger, wider, he takes up more of the screen acting wise - literally, and figuratively. Hackman reduces himself. This is not Popeye Doyle, or Captain Frank Ramsey in Crimson Tide. Brice doesn't want to be seen until he wants to be seen. He prefers to run his game from behind the scenes. Laughton's Janoth wants to be out front and on the front page. He is the face of his empire , and Laughton's performance is exactly that - out front and in your face. Laughton portrays Janoth as a man confident he's the biggest man in the room until almost the very end. It permeates everything he does from his chosen cadence and syntax, to his cigars, suits, and expressions. Meanwhile Hackman reminds me of those blankets used to hide the mess created by Vincent Vega after he shot Phil LaMarr in the head, it lasts as a subterfuge only so long as the conditions are favorable. His confidence goes in and out like a bad performance of a foreign accent. In the front he is smart, cock sure, dismissive even, but behind closed doors he shrinks , cowers, questions himself, its maybe the largest difference between any two characters in either of the films. The scenes that show them post murder and identified as the murderers make readily clear their differences. Laughton is distressed, but not necessarily distraught, for all intensive purposes he is still rather composed, and in control. Control or the appearance of control is found in stillness. Laughton moves very little in the scene where he confesses his crime, Hackman is a wreck, he is completely distraught, and broken. He's all over the room, his body is up and down. He's crying, trying to regain composure, and then crying again.
