Filmworker is a 2017 American documentary film directed by Tony Zierra about Leon Vitali, a successful British actor who, after playing the role of Lord Bullingdon in the Stanley Kubrick-directed Barry Lyndon, gave up his acting career to work for decades as Kubrick’s assistant.

In Filmworker, Vitali’s experiences with Kubrick are brought together with previously unseen photos, videos, letters, notebooks and memos from his private collection.

After extensively interviewing Vitali, Zierra and his producing partner, Elizabeth Yoffe, decided that his story should be told and began shooting what would become Filmworker.

Film industry professionals featured in Filmworker include former and current Warner Bros. executives Julian Senior, Brian Jamieson, Warren Lieberfarb, Steve Southgate and Ned Price.

[10] Ann Hornaday in The Washington Post called Filmworker "movie love at its purest" and said that "Vitali’s story marked an incursion of the real world into Cannes in the very best sense, as a celebration of its anonymous inhabitants’ role in bringing our collective dreams to life.
