“Jessica is not really a singer, but she acted the singing so beautifully,” Marshall says.

“She’s just a beautiful, beautiful actress, and she went there.

It was exciting to see that change.

She’s a force, Jessica.

She’s incredible.”

“I really didn’t want to do too many stunt [castings],” Marshall says.

“The thing is that Jessica is an extraordinary actress,” Marshall says.

“I mean, quite young, but you’re able to see her work.
