He worked primarily on aerial unit photography, shooting helicopter exteriors for the film Bob & Carol & Ted & Alice.
[2] After being laid off, he fell in with Michael W. Watkins, who got him a job as a camera operator on the Jonathan Demme film Fighting Mad.
He spent much of the 1970s and early 1980s freelancing as an operator under DPs like William A. Fraker, Ric Waite, Harry Stradling Jr., and Bruce Surtees, shooting films like Bronco Billy, 48 Hrs., Pale Rider, and Beverly Hills Cop.
[2] Because of Eastwood's tendency to reuse the same crew from film-to-film, Green shot every Eastwood-directed film between 1986 and 2000, their final collaboration being Space Cowboys.
Since 2000, Green has worked on over fifteen films in genres ranging from science fiction (Serenity) to action (A Man Apart) to comedy (50 First Dates, The 40-Year-Old Virgin, Hot Tub Time Machine).
