Mark Sanderson is a Los Angeles based screenwriter, script consultant, and sometimes actor blessed to be living his childhood dream of making movies with thirty screenplays written in genres ranging from comedy to drama — from his sketch comedy writing and performing as a founding member of The Amazing Onionheads and writing for MTV, his spec sale, fourteen screenwriting assignments, television premieres, and worldwide distribution of his emotionally compelling films — the indie WWII feature I’ll Remember April, Lifetime Network's holiday films An Accidental Christmas and Deck the Halls, the stylish indie noir feature Stingers, action-packed thrillers USS Poseidon: Phantom Below (aka HereTv's Tides of War), SyFy Network's Sea Snakes (aka Silent Venom), LMN's thriller Mother of All Lies, and Lifetime's Mommy's Little Girl. Mark's films have opened festivals, premiered on Lifetime, LMN, HBO Canada, Fox, SyFy, HereTV, NBC Universal, and The Movie Network and have been distributed globally.

Mark’s creative passion for filmmaking began when he was just eleven years old and started making films with his friends. The Los Angeles Times coined them the "Beardless Wonders of Filmmaking" because they took their craft seriously and even created their own studio where they screened the films and charged admission. After graduating from UCLA Film School, Mark’s early screenplays garnered attention in writing competitions including a semi-finalist nod in the top 1% (a top 20 script) of all entries in the Academy’s prestigious Nicholl Fellowship, and a top 50 finalist placement in the Paramount Pictures based Chesterfield Writer’s Film Project originally created by Steven Spielberg.

Mark's produced films have gone on to be recognized at major festivals including a premiere and opening the Palm Springs Int. Film Festival, and premieres at the Hawaii Int. Film Festival, St. Louis Int. Film Festival, Rainbow Festival, Newport Beach Int. Film Festival, Fort Lauderdale Int. Film Festival, and nominated for the Starboy Award at the Oulu International Children's Film Festival in Finland.

Mark’s long association with award winning Hollywood filmmakers dates back to his first produced spec screenplay and has since worked with Academy Award® winning producers Paul Colichman (Academy Award® winner Gods & Monsters) and Mark R. Harris (Academy Award® winner Crash) — veteran directors Brian Trenchard-Smith, George Mendeluk, Fred Olen Ray, and the late Bob Clark — and has written/consulted on films starring Academy Award® acting nominees Seymour Cassel, the late Pat Morita, Haley Joel Osment, Tom Berenger, and Terence Stamp, Emmy® acting nominees Mark Harmon and James Hong, and Emmy® winner Barry Pepper.

Mark's new film Mommy's Little Girl premiered in March on the Lifetime Network and has five projects in development including the sci-fi comedy Area 54 with producer director Dan Harris and producer Mark Harris (Crash), the new paranormal talk show pilot Paranormal X, he completed work as the production consultant on the screenplay for the feature Bitter Harvest written and directed by George Mendeluk that stars Max Irons, Elizabeth Barks, Barry Pepper, and Terence Stamp, completed writing the first season of the web series Tribulations that is out to investors, and is publishing his new book A Screenwriter's Journey to Success in late 2016 on Amazon.
