The episode title "Pinewood" and the Pinewood Farms program are likely to be a nod to the Batman (1989) filming location, Pinewood Studios in Buckinghamshire, England.
Early in the episode, Sid Vicious' version of 'My Way' is played over a montage of Jim Gordon roughing up criminals for information on The Lady's whereabouts. Gary Oldman, who played Jim Gordon in Christopher Nolan's Batman Trilogy, also played Sid Vicious in 'Sid and Nancy'(1986).
Brett Azar played Len Sirkes, an entrepreneurial gangster in Jessica Jones season 1 (2015) on Netflix. Crossing over from MCU to DC, he is reduced to Hitman #3 that Jim Gordon (Ben McKenzie) beats up for information.
