Floyd Mutrux grew up in Houston and Los Angeles. After a stint with Second City in Chicago and New York, he went to Columbia University where he lived and went to school for the next five years. He then came back to L.A. in the 70's. That year he wrote and directed a documentary for Warner Bros. about heroin on the L.A. streets called Dusty and Sweets McGee. In a limited re-release, it was on of the most highly reviewed films of the year. He wrote and produced the action comedy Freebie and the Bean at Warner Bros., which became one of the biggest grossing films of the year. He then revised Scarecrow at Warner Bros., winner of Best Film in Cannes Film Festival. He wrote and directed Aloha, Bobby and Rose on a $600,000 budget. Released by Columbia, it grossed 35 times its cost at the summer box office, making it the sixth largest grossing picture of the year.
Floyd then directed American Hot Wax at Paramount; a cult hit for the last decade, which made many Best Picture lists, including The Village Voice as Best Picture and Best Director. In the 80's he created a half billion in revenue at the Paramount box office by originating the idea for The Untouchables, was the original director for Urban Cowboy, and the original writer/director for Up in Smoke. He also wrote/directed the Columbia teen hit Hollywood Knights. He sold the idea for Drug Wars to Michael Mann, which won the Emmy for the best mini-series in '89. In the early 90's he wrote American Me, Ford Fairlane, Blood In Blood Out, Mulholland Falls, and Hillside Strangler. He sold his original movie idea for Dick Tracy, which he executive produced at Disney. He then wrote and directed There Goes My Baby and although the picture got caught up in the Orion bankruptcy, it was a cult hit of the '94 Montreal and Mill Valley Film Festivals. In a front-page story, Variety called it the best "coming of age" film made since "American Graffiti". In the last couple of years Floyd has written a first draft of Punks Like Us (a nostalgic dark comedy about yuppies, New Regency), True Love Ways (a modern day High Noon set in Montana, Warner Bros.), and the new Ice Cube high school football comedy, now in re-acquirement from Universal. 
In 1995 Floyd sold a spec script, Common Ground for a million dollars to Paramount, with Mutrux producing and Travolta starring. It was the second million-dollar plus sale in two years. He sold Dancing With Myself, a musical for John Travolta, (about a Dance Doctor who makes house calls) to Fox for a million dollars with Suzanne de Passe and Mutrux producing, George Armitage (Gross Point Blank) directing. He wrote Teenage Idol, the story of Ricky Nelson, for Carsey-Werner "Moving Pictures." George Armitage is also attached as director. He also wrote Pablo Escobar for Sean Penn at Phoenix Pictures and the original story and screenplay for Inside-Out at Warner Bros. Mutrux is producing with director Richard Donner. He has written the story for a 50's Broadway musical, Moon Dog Matinee, about the early days of the music business, a.k.a. 'Goodfellas' for rock and roll.

In the last twenty five years Floyd has written and sold over fifty screenplays.
