Mark Sanderson

Mark Sanderson (aka Scriptcat) 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 a wide range of genres—from his sketch comedy writing and performing as a founding member of The Amazing Onionheads sketch troupe, writing for MTV, his spec sale and sixteen screenwriting assignments, to the television premieres and worldwide distribution of his nine films.


Mark's films have also been recognized at festivals including a premiere and opening the Palm Springs Int. Film Festival, premieres at the Hawaii Int. Film Festival, St. Louis Int. Film Festival, The Rainbow Festival in Hawaii, Newport Beach Int. Film Festival, Fort Lauderdale Int. Festival, and nominated for the Starboy Award at the Oulu Int.

His new book, "A Screenwriter's Journey to Success" is now available on Amazon.
