One of the most resonant percussions Southern literature has had on our culture has been on the silver screen. William Faulkner worked as a screenwriter, Tennessee Williams’ plays naturally became films and the American cinema is rife with Southern influence.

Demopolis product Margaret Tallichet was an aspiring actress when she moved from Dallas to Hollywood then married William Wyler, an established director with the Oscar-winning “Jezebel” already among his credits. The couple became close friends with Lillian Hellman, another Demopolis descendant and playwright of “The Little Foxes” and “The Children’s Hour.”

The Wylers’ daughters Catherine and Melanie will be on hand March 21 in Mobile for Trailfest 2015. At the Ben May Main Library at 2 p.m., they will introduce two of their father’s films and a special screening of “Directed by William Wyler,” a documentary produced by Catherine Wyler.

The elder Wyler was a Hollywood legend and Oscar-laden director with films such as “Funny Girl,” “Roman Holiday,” “Wuthering Heights,” “Dodsworth,” “Ben-Hur” and “The Best Years of Our Lives.” In “Directed by William Wyler,” the director was interviewed about his career just three days before his death on July 27, 1981. Actors and actresses he guided to acclaim and Oscars are also interviewed for the film including Bette Davis, Gregory Peck, Laurence Olivier, Audrey Hepburn and Barbra Streisand.

The film on Wyler will be followed by a screening of “Jezebel.”
