#1 - Executive Suite, 1954 starring William Holden is great. Back-stabbing, dissimulation and betrayal abound. Also starring June Allyson, Barbara Stanwyck, Fredric March, Walter Pidgeon, Louis Calhern (The Asphalt Jungle), Dean Jagger (Bad Day at Black Rock) and Shelley Winters. "When the head of a large manufacturing firm dies suddenly from a stroke, his vice presidents vie to see who will replace him." #2 - Margin Call As a distant third I'd also include Blackberry (2023)
