The beloved movie musical Mamma Mia! was released in theaters 15 years ago and the cast and crew recently took a look back at the making of the hit film for a Vogue oral history feature.

Casting directors Priscilla John and Ellen Lewis chatted about all of the actors that they saw for the roles of Sky and Sophie.

We already learned about the 17 actresses who auditioned for the role of Sophie, which went to Amanda Seyfried. Now it’s time to learn about the six actors considered for Dominic Cooper‘s role of Sky.

“We really fought for Dominic, because the studio said they thought he wasn’t fun enough. They saw him as a bad boy and seemed to want someone a bit more saccharine,” Priscilla said.

Dominic added, “I remember thinking not to even bother auditioning, as I thought I was never going to get it. I don’t consider myself a musical theater person at all, so I was a bit skeptical. But I remember being persuaded by the lovely Priscilla to suck it up.”
