All the President's Men dealt with the impeachment of Richard Nixon, while Lumet's Network portrayed greed and narcissism in both American society and television media. The film won Oscars for Best Actor (Peter Finch), Best Actress (Faye Dunaway), Best Supporting Actress (Beatrice Straight), and Best Screenplay (Paddy Chayefsky). Thanks to a stellar cast, experienced director, and a poignant story, Network became one of the largest critical successes of 1976.

Title: AACTA Award for Best Actor in a Leading Role
Content:  until 1975, the awards for Best Actor and Best Actress were awarded in a single category for Best Performance. In 1971 the prize was given to Monica Maughan over fellow nominee Peter Cummins, who received a special mention for his performances in the films Some Regrets, The Hot Centre of the World (1971 short film), Bonjour Balwyn and Carson's Watermelons. From 1972 to 1975, the single award was handed out to the best actor and actress of the respective award giving years, with honourable mentions made to supporting casts. From 1976 to the present, the accolade has been handed out as a separate award for Best Actor in a Leading Role. Candidates for this award must be human and male, and cannot be nominated for the same role in the supporting actor category.
Title: 47th Academy Awards
Content:  The 47th Academy Awards were presented Tuesday, April 8, 1975, at the Dorothy Chandler Pavilion in Los Angeles, California, honoring the best films of 1974. The ceremonies were presided over by Bob Hope, Shirley MacLaine, Sammy Davis Jr., and Frank Sinatra. This was the last year NBC aired the ceremonies before ABC secured broadcasting rights, which they still hold to this day. The success of The Godfather Part II was notable; it received twice as many Oscars as its predecessor (six) and duplicated its feat of three Best Supporting Actor nominations (as of the 93rd Academy Awards, the last film to receive three nominations in a single acting category). Between the two of them, father and son Carmine and Francis Ford Coppola won four awards, with Carmine winning for Best Original Dramatic Score (with Nino Rota) and Francis for Picture, Director, and Best Screenplay Adapted from Other Material (with Mario Puzo). This was the only Oscars where all nominees in one category (where the category had five nominees) were released by the same studio: all five Best Costume Design nominations were for films released by Paramount Pictures.

In a surprise win (Bing Crosby was the favored nominee), Brando received his first Oscar for his performance in On the Waterfront, which is now seen as one of the greatest Best Actor wins in Oscar history. The win was a culmination of four consecutive Best Actor nominations for Brando (starting with A Streetcar Named Desire in 1951), a record that remains unmatched to this day. Grace Kelly won Best Actress for The Country Girl in an even bigger upset. Judy Garland, who was heavily favored to win Best Actress for the movie A Star Is Born, could not 
Title: 45th Academy Awards
Content:  The 45th Academy Awards were presented Tuesday, March 27, 1973, at the Dorothy Chandler Pavilion in Los Angeles, California, honoring the best films of 1972. The ceremonies were presided over by Carol Burnett, Michael Caine, Charlton Heston, and Rock Hudson. The ceremony was marked by Marlon Brando's boycott of the Oscars and his sending of Sacheen Littlefeather to explain why he would not show up to collect his Best Actor award for The Godfather, and by Charlie Chaplin's only competitive Oscar win for Best Original Dramatic Score for his 20-year-old film Limelight, which was eligible because it did not screen in Los Angeles until 1972. Chaplin had received honorary Academy Awards in 1929 and 1972. Cabaret, Bob Fosse's adaptation of the Broadway stage musical, set a record for the most Oscars won without winning Best Picture. Best Picture winner The Godfather received only three Academy Awards. This year was the first time that two African American women received nominations for Best Actress. This was also the first year when all the Oscar winners were brought out on stage at the end of the ceremony. The show drew a television audience of 85 million viewers.
Title: 7th Academy Awards
Content:  The 7th Academy Awards, honoring the best in film for 1934, was held on February 27, 1935, at the Biltmore Hotel in Los Angeles, California. They were hosted by Irvin S. Cobb. Frank Capra's influential romantic comedy It Happened One Night became the first film to perform a "clean sweep" of the top five award categories: Best Picture, Best Director, Best Actor, Best Actress, and Best Screenplay. This feat would later be duplicated by One Flew Over the Cuckoo's Nest in 1976 and The Silence of the Lambs in 1992. It also was the first romantic comedy to be named Best Picture, and the first to win two acting Oscars. For the first time, the Academy standardized the practice – still in effect – that the award eligibility period for a film would be the preceding calendar year. This was also the first of only two years in which
