Three Little Words is a 1950 American musical film biography of the Tin Pan Alley songwriting partnership of Kalmar and Ruby and stars Fred Astaire as lyricist Bert Kalmar, Red Skelton as composer Harry Ruby, along with Vera-Ellen and Arlene Dahl as their wives, with Debbie Reynolds in a small but notable role as singer Helen Kane.
 The film, released by Metro-Goldwyn-Mayer, was written by Academy Award winning screenwriter George Wells, directed by Richard Thorpe and produced by Jack Cummings.
 Harry Ruby served as a consultant on the project, and appears in a cameo role as a baseball catcher.
 It was the third in a series of MGM biopics about Broadway composers; it was preceded by "Till the Clouds Roll By" (Jerome Kern, 1946) and "Words and Music" (Rodgers and Hart, 1948) and followed by "Deep in My Heart" (Sigmund Romberg, 1954).
The 18th Academy Awards was the first such ceremony after World War II.
 As a result, the ceremony featured more glamour than had been present during the war.
 Plaster statuettes that had been given out during the war years were replaced with bronze statuettes with gold plating.
 Despite this, director Billy Wilder's grim and socially significant drama "The Lost Weekend" took the top honors.
 It became the first film to win both the Academy Award for Best Picture and the Palme d'Or.
 Joan Crawford was absent, claiming she had pneumonia (although it was said it was because she was sure she would not win the Academy Award for Best Actress for "Mildred Pierce").
 As it turned out she did win, and the award was delivered to her while in bed that night.
Ruby Gentry is a 1952 film directed by King Vidor and starring Jennifer Jones, Charlton Heston and Karl Malden.
"Ruby" is the 1952 theme song for the film "Ruby Gentry" starring Jennifer Jones, written by Mitchell Parish and Heinz Roemheld.
 It was a 1960 hit for Adam Wade accompanied by George Paxton & His Orchestra with The Bel-Aire Singers.
 Wade's B-side was "Too Far" written by Pat Lambert and Bob Haymes.
 The song was also performed by Ray Charles in 1960.
The Academy Award for Best Film Editing is one of the annual awards of the Academy of Motion Picture Arts and Sciences (AMPAS).
 Nominations for this award are closely correlated with the Academy Award for Best Picture.
 For 33 consecutive years, 1981 to 2013, every Best Picture winner had also been nominated for the Film Editing Oscar, and about two thirds of the Best Picture winners have also won for Film Editing.
 Only the principal, "above the line" editor(s) as listed in the film's credits are named on the award; additional editors, supervising editors, etc. are not currently eligible.
 The nominations for this Academy Award are determined by a ballot of the voting members of the Editing Branch of the Academy; there were 220 members of the Editing Branch in 2012.
 The members may vote for up to five of the eligible films in the order of their preference; the five films with the largest vote totals are selected as nominees.
 The Academy Award itself is selected from the nominated films by a subsequent ballot of all active and life members of the Academy.
 This process is essentially the reverse of that of the British Academy of Film and Television Arts (BAFTA); nominations for the BAFTA Award for Best Editing are done by a general ballot of Academy voters, and the winner is selected by members of the editing chapter.
