Kinds of American Film Comedy: Six Core Genres and Their Literary Roots ((forthcoming from McFarland Press))
Gehring has signed a new book contract for a second anthology collection of selected Gehring essays, ((2024))
Gehring is writing a contracted for book ( McFarland Press ) on the secret behind the ongoing acclaim of the American Film Institute's ( AFI ) favorite 20th century comedy -- SOME LIKE IT HOT.
Gehring is outlining a novelized book length interaction between Charlie Chaplin and W. C. Fields set in 1944. At that time Chaplin was afraid scandal might threaten his career, while Fields' alcoholism was essentially ending his work and life. The novel is inspired by Steve Martin's play, PICASSO AT THE LAPIN AGILE ( a bar ), in which Einstein and Picasso meet in 1904. The twist here is that both men are near transformative moments in their young lives.
