Frank Langella is under investigation for alleged sexual harassment on the set of a Netflix project ... TMZ has learned.
A production source tells us there have been allegations of inappropriate conduct by Langella made within the last couple weeks on the set of the limited series "The Fall of the House of Usher." We're told there's currently an investigation into what happened, but Langella has not been fired or suspended from the series.
As for what exactly happened, a source close to production tells us the 84-year-old actor allegedly made an inappropriate joke that was sexual in nature. Our sources also say in the context of his performance, possibly during rehearsal, he touched the leg of a female costar, and further drew attention to the action when he jokingly said something like "Did you like that?"
The show has been filming in British Columbia, Canada ... we reached out to the local police department who says nothing has been reported to them involving Frank.
