After taking over a subway station in The Bronx and the streets of DUMBO, that Joaquin Phoenix Joker movie has continued filming around town this month in an effort to transform the city into a gritty '80s montage. We already knew from the official logline that the movie "is not only a gritty character study, but also a broader cautionary tale," but we didn't realize the filmmakers would take that last part so seriously. According to reports, extras were locked on a subway car for several hours during filming recently—to the point that some started peeing on the tracks.

TMZ reports that while filming a recent scene inside a Brooklyn subway station, extras were locked in a train car and allegedly denied their break after two hours of work. "The extras started banging on the subway doors asking to be let out because people needed to use the bathroom, but they were kept inside and eventually resorted to pissing on the tracks through the small spaces between cars," TMZ writes.

Real New Yorkers who experience hours-long subway delays everyday will appreciate director Todd Phillips's (Road Trip) dedication to cinéma vérité.

TMZ adds that the Screen Actors Guild has received a complaint about a break time violation; Warner Bros. confirmed that they are looking into the incident as well.

You can check out pee-free videos below from the recent Brooklyn subway shoots, which Screencrush thinks were shot along the F line at the Church Avenue and 18th Avenue stations. SPOILER ALERT: it turns out The Joker is one of those dudes who thinks it's totally rebellious to smoke inside the subway station.
