Question: This actor was cast in The Best Man and Invasion of the Body Snatchers.
Context: Invasion of the Body Snatchers is a 1956 American science fiction horror film produced by Walter Wanger, directed by Don Siegel, that stars Kevin McCarthy and Dana Wynter.  The black and white film, shot in Superscope, was partially done in a film noir style.  Daniel Mainwaring adapted the screenplay from Jack Finney's 1954 science fiction novel "The Body Snatchers".  The film was released by Allied Artists Pictures on a double bill with the British science fiction film "The Atomic Man". Jack Finney (October 2, 1911 – November 14, 1995) was an American author.  His best-known works are science fiction and thrillers, including "The Body Snatchers" and "Time and Again".  The former was the basis for the 1956 movie "Invasion of the Body Snatchers" and its remakes. Body Snatchers is a 1993 American science fiction horror film directed by Abel Ferrara and starring Gabrielle Anwar, Billy Wirth, Terry Kinney, Meg Tilly, Christine Elise, R. Lee Ermey and Forest Whitaker.  It is loosely based on the 1955 novel "The Body Snatchers" by Jack Finney. Kevin McCarthy (February 15, 1914 – September 11, 2010) was an American stage, film, and television actor who gave over two hundred television and film performances.  He is best remembered for portraying the male lead in the horror science fiction film "Invasion of the Body Snatchers" (1956). Invasion of the Body Snatchers is a 1978 American science fiction horror film directed by Philip Kaufman, and starring Donald Sutherland, Brooke Adams, Veronica Cartwright, Jeff Goldblum and Leonard Nimoy.  Released on December 22, 1978, it is a remake of "Invasion of the Body Snatchers" (1956), which is based on the novel "The Body Snatchers" by Jack Finney.  The plot involves a San Francisco health inspector and his colleague who discover that humans are being replaced by alien duplicates; each is a perfect copy of the person replaced, only devoid of human emotion. Veronica A. Cartwright (born 20 April 1949) is an English-born American actress who has worked mainly in American film and television in a career spanning six decades.  As a child actress she appeared in supporting roles in "The Children's Hour" and "The Birds".  She is perhaps best known for her roles in the science fiction films "Invasion of the Body Snatchers" (1978) and "Alien" (1979), for which she won a Saturn Award for Best Supporting Actress. Invasion of the Bunny Snatchers is a Bugs Bunny short subject directed by Greg Ford and Terry Lennon and released in 1992.  The cartoon was intended for theatrical release but eventually aired as part of the television special "Bugs Bunny's Creature Features".  Its premise is modeled after "Invasion of the Body Snatchers", and it is considered subversive, critical of the greed of its production studio Warner Bros., and a lampoon of cheaply-drawn animation. The Best Man is a 1964 political drama film directed by Franklin J. Schaffner with a screenplay by Gore Vidal based on his play of the same title.  Starring Henry Fonda, Cliff Robertson, and Lee Tracy, the film details the seamy political maneuverings behind the nomination of a presidential candidate.  The supporting cast features Edie Adams, Margaret Leighton, Ann Sothern, Shelley Berman, Gene Raymond, and Kevin McCarthy. Invasion is an American science fiction television series that aired on ABC for one season beginning in September 21, 2005.  Somewhat similar to "Invasion of the Body Snatchers", the show told the story of the aftermath of a hurricane in which water-based creatures infiltrate a small Florida town and begin to take over the bodies of the town's inhabitants through a cloning process (first by merging with and then unknowingly replacing them).  The show was produced by Shaun Cassidy Productions and Warner Bros.  Television. Pod people (also known as The Body Snatchers) is a nickname given to an alien species featured in the 1955 novel "The Body Snatchers" by Jack Finney, the 1956 film "Invasion of the Body Snatchers", the 1978 remake of the same name and the 1993 film "Body Snatchers".  Not to be confused with the 2007 film "Invasion of the Pod People" though they share similar themes.
