Back in the 1970s, the only entertainment you’d find in New York’s Times Square was of the... er,  "adult" variety.

HBO’s new series The Deuce explores those seedier days when the crossroads of the world gave rise to the adult film industry. Maggie Gyllenhaal and James Franco star in the drama created by George Pelecanos and David Simon (The Wire).  

Check out the clip above, where Franco—who also directs several episodes—discusses the challenges in recreating a bygone era in today’s more family-friendly Times Square.

HBO's The Deuce debuts Sept. 10 at 9 p.m. ET, but you can watch a special advance premiere now on HBO NOW and HBO GO
