Development The film was based on a screen story by Irwin Shaw,
Education of the Heart. RKO purchased it in April 1946. In June Robert Sparks was assigned the job of producing and Charles Schnee the job of writing the screenplay. In May 1948 the title was changed to
Interference.
Cast In May 1948 RKO announced
Jane Greer and
Robert Mitchum would play the leads. Neither ended up in the final film. Victor Mature was under contract to
20th Century Fox but had an obligation to make a movie at RKO which dated from before the war. He was announced for
Battleground and
Mr Whiskers before eventually being cast in
Interference in June 1948. On the same day this was confirmed he was also announced for the lead in
Samson and Delilah, which would be filmed after
Interference. (He would end up playing
Mr Whiskas which became
Gambling House.) In June Jacques Tourneur was assigned to direct. Other key roles went to Sonny Tufts, Lucille Ball and Lizabeth Scott.
Shooting There was a great deal of turbulence at RKO at the time due to the fact that
Howard Hughes had bought the studio and head of production
Dore Schary had resigned. Films such as
Battleground,
Bed of Roses and
Setup were cancelled. However
Interference went ahead started July 12, 1948. Tourneur called the film "a hard one" for him because he had no interest in football. He later said it was "a very bad film." The film was originally meant to end with Mature's character leaving his wife for Ball. However it was rewritten during filming so Mature stayed with his wife. ==Release==
