Calvin Coolidge

On August 11, 1924, Theodore W. Case, using the Phonofilm sound-on-film process he developed for Lee de Forest, filmed Coolidge on the White House lawn, making "Silent Cal" the first president to appear in a sound film.

John F. Kennedy

It was during his re-election campaign that Kennedy's press secretary at the time, Robert E. Thompson, put together a film entitled The U.S. Senator John F. Kennedy Story, which exhibited a day in the life of the Senator and showcased his family life as well as the inner workings of his office to solve Massachusetts-related issues.

Ronald Reagan

He earned his first screen credit with a starring role in the 1937 movie Love Is on the Air, and by the end of 1939, he had appeared in 19 films, including Dark Victory with Bette Davis and Humphrey Bogart. Before the film Santa Fe Trail with Errol Flynn in 1940, he played the role of George Gipp in the film Knute Rockne, All American; from it, he acquired the lifelong nickname "the Gipper". In 1941, exhibitors voted him the fifth most popular star from the younger generation in Hollywood.

Reagan played his favorite acting role in 1942's Kings Row, where he plays a double amputee who recites the line "Where's the rest of me?"—later used as the title of his 1965 autobiography. Many film critics considered Kings Row to be his best movie, though the film was condemned by The New York Times critic Bosley Crowther.

Kings Row made Reagan a star—Warner immediately tripled his salary to $3,000 a week. Shortly afterwards, he received co-star above-the-title billing with Flynn – who was still a huge star at the time – in Desperate Journey (1942). In April 1942, Reagan was ordered to military active duty in San Francisco and never quite became a big first-rank film star despite playing the lead in numerous movies. After his wartime military service he co-starred in such films as The Voice of the Turtle, John Loves Mary, The Hasty Heart, Bedtime for Bonzo, Cattle Queen of Montana, Tennessee's Partner, Hellcats of the Navy (the only film in which he appears with Nancy Reagan), and his one turn at playing a vicious villain, in the 1964 remake The Killers (his final film) with Lee Marvin and Angie Dickinson. Throughout his film career, Reagan's mother answered much of his fan mail.

Reagan landed fewer film roles in the late 1950s and moved into television. He was hired as the host of General Electric Theater, a series of weekly dramas that became very popular. His contract required him to tour General Electric (GE) plants 16 weeks out of the year, which often demanded that he give 14 talks per day. He earned approximately $125,000 (equivalent to $1.1 million in 2020) in this role. The show ran for ten seasons from 1953 to 1962, which increased Reagan's national profile. On January 1, 1959, Reagan was the host and announcer for ABC's coverage of the Tournament of Roses Parade. In his final work as a professional actor, Reagan was a host and performer from 1964 to 1965 on the television series Death Valley Days. Following their marriage in 1952, Ronald and Nancy Reagan, who continued to use the stage name Nancy Davis, acted together in three TV series episodes, including a 1958 installment of General Electric Theater titled "A Turkey for the President".
