Sounds like Christopher Nolan's Oppenheimer is really going to earn that "R" rating
The R-rated film will apparently feature "prolonged full nudity" for stars Cillian Murphy and Florence Pugh

Of the various things Christopher Nolan likes to film—explosions, things moving backwards, shockingly angular men—human sexuality tends to rank pretty low. That might be about to change, though, as both Nolan and (very angular) star Cillian Murphy have confirmed that Nolan’s upcoming film Oppenheimer is going to dive pretty thoroughly into its subject’s sex life, including, per a recent Guardian interview with Murphy, “prolonged full nudity for Murphy and Florence Pugh.” That’s in addition to what are being described as “complicated” scenes between Murphy and his A Quiet Place Pt. II co-star Emily Blunt, who plays Oppenheimer’s wife, Kitty; we have no earthly clue what “complicated” means in this circumstance, but Murphy described them as “pretty heavy” and then said he was sworn to secrecy about anything else, so… yeah.
