NEW YORK –  Patti LuPone isn’t going to keep again. 

Scenario in level: a 2017 purple-carpet interview, in which she railed versus Donald Trump. The viral clip finally led director Ari Aster to solid the Broadway star as Mona in “Beau Is Worried,” participating in the dementedly overbearing mom to Joaquin Phoenix’s schlubby hero. 

“Honestly, when we ended up considering of who could perform Mona, I observed a 30-2nd clip of her on a crimson carpet and she was just terrifying, in a excellent way,” recalls Aster, a longtime lover of LuPone’s theater perform. “It was just clear that it was her.”
