Enola stays with her so much that Brown’s husband, Jake Bongiovi, who also worked on the film, says she sometimes takes the character home with her.

Brown agrees that Enola definitely stays with her and jokes that the teen detective’s high standards can also follow her home.

“Enola is high maintenance and sometimes I go home and I’m like, ‘Why does the bed look like that?’ Then I’m like, Millie, chill, you do not need to speak like that.”

What she is most protective of, she says, is Enola’s intelligence.

Partridge remembers filming once stopping “for five hours” because Brown felt Enola would have worked something out sooner.

“She was like, no, no, no, Enola would know that flag is from this country and she would have worked that out.”

Brown cuts in, laughing. “Oh please, it was not five hours,” she says. Partridge revises it to three, but Brown is still not having it.

“He’s such a liar, it was not three hours,” she says.

She insists she is usually “the biggest girl on getting things done quickly”, but says this mattered.

“Like those fans who critique absolutely everything, I want to make sure I’m bringing to life a plot that makes sense and characters that people can believe in.”
