Emmett Evan "Van" Heflin Jr. was an American theatre, radio, and film actor. He played mostly character parts over the course of his film career, but during the 1940s had a string of roles as a leading man. Heflin won the Academy Award for Best Supporting Actor for his performance in Johnny Eager (1942). He also had memorable roles in Westerns such as Shane (1953), 3:10 to Yuma (1957), and Gunman's Walk (1958).

The Academy Award for Best Supporting Actor is an award presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS). It has been awarded since the 9th Academy Awards to an actor who has delivered an outstanding performance in a supporting role in a film released that year. The award is traditionally presented by the previous year's Best Supporting Actress winner. In lieu of the traditional Oscar statuette, supporting acting recipients were given plaques up until the 16th Academy Awards, when statuettes were awarded to each category instead.
