Robert Pattison revealed in an interview with The Irish Times that he was forbidden from revealing his audition for the part to anyone - including his Tenet director Christopher Nolan. Except, considering Nolan is perhaps the master of secrets, Pattinson’s “lie” didn’t pass.
“I had to be really secretive about Batman stuff,” the actor said. “So I had to lie to Chris about having to go for a screen test.”
“I said I had a family emergency,” Pattinson explained. “And as soon as I said ‘it’s a family emergency’ he said: ‘You’re doing the Batman audition, aren’t you?‘”
