In his autobiography "Timebends", Arthur Miller said that Lee J. Cobb was his favorite Willy Loman.

In the scene where Howard (Bernie Kopell) is showing Willy (Lee J. Cobb) his new "wire recorder", you hear Howard's "son" reciting state capitals. The voice of Howard's "son" was June Foray, using the same voice she used for Rocket "Rocky" J. Squirrel in The Bullwinkle Show (1959).

In his autobiography "Timebends", Arthur Miller speculated that his unconscious mind picked the name "Loman" for Willy Loman, the protagonist of "Death of a Salesman", based on his conscious experience of being thrilled by The Testament of Dr. Mabuse (1933), which featured a character named "Inspector Lohmann".

The original Broadway production of "Death of a Salesman" by Arthur Miller opened at the Morosco Theater on February 10, 1949, ran for seven hundred forty-two performances, and won the 1949 Tony Award (New York City) for the Best Play. Lee J. Cobb re-created his stage role in this television production.

"Death of a Salesman" won the Pulitzer Prize in Drama in 1949.

This television drama was video taped in Los Angeles, California, at the CBS Television City (studios), located at Beverly Boulevard and Fairfax Avenue. Tom John, an established New York City Television Designer and Art Director was hired to design the production. Tom employed his New York City assistant, Chuck Murawski as his Assistant Art Director, flying Chuck from New York City for the four-week prep period. The television play adaptation was rehearsed in the mezzanine rehearsal rooms adjacent the third floor Art Department. (This rehearsal hall was later used by Carol Burnett for her show's rehearsal, and for her private exercise club meetings during The Carol Burnett Show (1967) weekly schedule.) During the production period, Tom, and another "Hollywood designer friend", Jim Trittipo, who often visited each other during the production schedule, late one midnight, were in the CBS Art Department, an original gauche film production sketch from Gone with the Wind (1939) had graced the walls of the Art Department for years. The pair decided to steal the "burning of Atlanta" sketch, using a mat knife, slicing the illustration down the middle, so that each could have a "souvenir".
