Good Luck To You, Leo Grande is a mouthful in more ways than one.The great Emma Thompson stars as Nancy Stokes, a 55-year-old widow who hires a sex worker, Leo Grande, so that she can enjoy a night of exploration and pleasure.

A bit out of practice and insecure—she says she’s never had an orgasm—Nancy even prepares a to-do list for her time with Leo (“Number one: I perform oral sex on you,” the list goes on).True to his last name, Grande has a lot to offer Nancy.

It’s an incredible breakout for relative newcomer Daryl McCormack, an Irish stage actor perhaps best known for his recurring role in Netflix‘s Peaky Blinders.
