Scarlett said that director Greg was a 'huge fan' of Colin.

'And Colin's, like, I think he had to do it because it's like in our prenuptial agreement. If I have to do something, he has to be there to support me,' Scarlett said prompting Jimmy to burst into laughter.

Jimmy asked Scarlett if runs lines with Colin, referring to the practice of rehearsing dialog with someone.

'I run lines with him, which is great. You'd think that would be very convenient because you have a a partner there to help you out, you can learn your lines, you know, for tomorrow, whatever,' Scarlett said.

'He does like real serious, he really commits to the line reading. And it's not always the performance I want it to be,' she added.

'You don't want any performance,' chimed in Jimmy.

'No. I'm like, just say the lines,' Scarlett said.

Scarlett shared that Colin adds big dramatic pauses and really gets into it until she can't focus.
