Lily James cannot fight the music. In the title role of 2015’s handsome Cinderella rework, her beautiful singing served as a plot point, attracting a suitor to her like a sailor drawn in by a siren’s song. She’s gotten another bump in visibility as the female lead of Baby Driver, another film fundamentally oriented around music. (The swooningly romantic scene in which she and her crush Baby share a pair of earbuds at a laundromat is already a fan-favorite.) Now she’s taken her next major role, and it’s sure to put her vocal cords through their paces.

Here we go again, more casting news about Mamma Mia!: Here We Go Again. The Hollywood Reporter has the exclusive that James has joined the cast already including returning talents Amanda Seyfried, Meryl Streep, Pierce Brosnan, and Colin Firth. Though she’s the official cast newbie, hers will still be a starring role; the new film splits its time between the present-day and extended flashbacks to the early days of Donna, and James will play the younger version of Streep’s character. And with a soundtrack featuring ABBA tracks that didn’t make the cut for the first film as well as a handful of reprises, James should start doing her vocal warm-ups now.

That said, I cannot imagine a more terrifying task for a young performer than being told, “Make us believe you could grow up to be Meryl Streep.” James can handle the singing and dancing no problem, but this could present her with an unprecedented challenge as an actress. Has she seen Kramer Vs. Kramer? Who could possibly want to be compared to that!?
