Mark Sanderson (aka @Scriptcat) is a Los Angeles based screenwriter, author, script consultant and sometimes actor blessed to be living his childhood dream of making movies with over two-dozen screenplays written in genres ranging from comedy to drama.

Mark's newest film, "My Daughter Vanished" will premiere in the fall of 2018.

Mark's films have premiered on Lifetime Network, LMN, SyFy, Fox, HereTV, HBO Canada, Christmas 24, and NBC/Universal, The Movie Network, and have been distributed globally.

Mark has five projects in development including among others the sci-fi TV series "Paranormal X" with director Dan Harris and producer Mark Harris (Crash), and the webseries "Tribulations" with director Joe Palese and producer Julie Helton (The Broken Ones). Mark was also the story editor/production consultant on the feature "Bitter Harvest" directed by George Mendeluk that stars Max Irons, Samantha Barks, Terence Stamp, and Barry Pepper. The indie film was released theatrically around the world in February 2017.
