In a 2019 email to producer Randall Emmett, Pacino suggested adding another shooting day to the film "to help [Williams] give a better performance".^[10] "Let's do this Randall. I'm not going for the A's or the B's. I’m going for something between C and B. I don't like Ds," wrote Pacino, "And, as long as you put the effort in with what you know about filmmaking and Michael too I'm sure we'll get to a B−. And that's good enough for me, if it's good enough for you."^[2] Pacino also complained that Williams was interfering with director Michael Polish's editing process. "My thought Randall is very simple. She is not a professional. ... Someone has to say 'back off a second dear, we're completing the film still, take a look when it's ready'," Pacino wrote to Emmett.^[2]
