Amanda Lucas, the daughter of Star Wars creator George Lucas, is an MMA fighter. This trailer is for a documentary about her, called Lucas, due for release later this year.
It's being made by Briton Bobby Razak, a director who makes MMA docs like this (as well as commercials) for a living. You can check out more of his work below.
