Preston Sturges
Preston Sturges (born Edmund Preston Biden; August 29, 1898 – August 6, 1959) was an American playwright, screenwriter, and film director.
In 1941, he won the Oscar for Best Original Screenplay for the film "The Great McGinty", his first of three nominations in the category.
Sturges took the screwball comedy format of the 1930s to another level, writing dialogue that, heard today, is often surprisingly naturalistic, mature, and ahead of its time, despite the farcical situations.
It is not uncommon for a Sturges character to deliver an exquisitely turned phrase and take an elaborate pratfall within the same scene.
Prior to Sturges, other figures in Hollywood (such as Charlie Chaplin, D. W. Griffith, and Frank Capra) had directed films from their own scripts, however Sturges is often regarded as the first Hollywood figure to establish success as a screenwriter and then move into directing his own scripts, at a time when those roles were separate.
Sturges famously sold the story for "The Great McGinty" to Paramount Pictures for $1, in return for being allowed to direct the film.
Christmas in July (film)
Christmas in July is a 1940 comedy film written and directed by Preston Sturges based on his 1931 play "A Cup of Coffee".
It was Sturges' second film as writer-director, after "The Great McGinty", and stars Dick Powell and Ellen Drew.
