In a 2018 interview, Alan Hicks described how he came to be involved in the film: "Our journey with Quincy Jones, he was involved with Keep on Keepin' On (2014), which is my first film. We got to know each other through that, and once that had finished, I met his daughter Rashida Jones and we've become good friends. She had already started on this documentary kind of by filming him piece by piece, and she came up and asked me if I would co-direct the film with her. We said yes and all of sudden we started following Quincy, Rashida and I and two camera guys (a guy called Adam Hart and another bloke named Rory Marx Anderson), and we followed him for three years filming. We filmed 800 hours worth of vérité footage, which is a lot. Then we also collected 2,000 hours of archival footage."
In a 2018 interview with The Hollywood Reporter, Rashida Jones spoke about her filmmaking influences in general and this film in particular: "I watched a LOT of TV growing up and I feel like it's the storytelling aspects. Any film by Mike Nichols was the reason I wanted to become a filmmaker. Because it doesn't matter who the people were in his movie, there's pathos and heart and intelligence. The reason I thought it would maybe be a good idea to make Quincy was I saw this movie, Still Bill (2009), about Bill Withers that I thought was so tender and it was such a great balance of a personal story and educating people who weren't fans of his. I just was really moved by that movie."
