When Jane Rosenthal appeared at a Q&A prior to a screening of “The Irishman” — at Tribeca Film Institute’s fall benefit at the Museum of the Moving Image — the power producer warned the crowd, “Use the bathroom now.”

“There was a rush out of the theater,” said a spy at the 3 ½-hour Martin Scorsese epic.

Also at the event for the Netflix film were star and producer Robert De Niro, as well as Edward Burns and Keegan-Michael Key.
