John Larkin was an American actor whose nearly 30-year career was capped by his 1950s portrayal of two fictional criminal attorneys – Perry Mason on radio and Mike Karr on television daytime drama The Edge of Night. After having acted in an estimated 7,500 dramatic shows on radio, he devoted his final decade to television and, from April 1962 to January 1965, was a key member of the supporting cast in two prime-time series and made at least twenty major guest-starring appearances in many of the top drama series of the period.

The Satan Bug is a 1965 American crime science fiction suspense film from United Artists, produced and directed by John Sturges, that stars George Maharis, Richard Basehart, Anne Francis, and Dana Andrews. The screenplay by James Clavell and Edward Anhalt was loosely based on the 1962 novel of the same name by Alistair MacLean, written under the pseudonym Ian Stuart. The film score was composed by Jerry Goldsmith. The film featured the first use of a stabilized camera mount, invented by Nelson Tyler, placed on a helicopter.
