Old Focals Architect - Al Pacino - Once Upon a Time in Hollywood
The Architect frame is made by Old Focals, a company founded and run by Russ Campbell, specialized in providing refurbished vintage eyewear and retro style sunglasses to celebrities, films and series (see more glasses provided by Old Focals here).
Other glasses in the film, for example the gold sunglasses worn by Brad Pitt and Leonardo DiCaprio, are probably real vintage frames also provided by Old Focals.
Once Upon a Time in Hollywood is a 2019 black comedy drama film written and directed by Quentin Tarantino, his ninth film. The film stars Leonardo DiCaprio, Brad Pitt, Margot Robbie, Kurt Russell, Timothy Olyphant, Dakota Fanning, Luke Perry, Margaret Qualley, and Al Pacino.
