Despite the fact that Suki and Lily are most likely too young to remember the early noughties in all their hipster jeans and cami vest glory, the two actresses wear pastel denim and boho chic like pros in the film which is set over a decade ago.
Based on the novel by Cecilia Ahern, the author behind PS I Love You, the film follows best friends Alex (Sam Claflin) and Rosie (Lily Collins) from when they meet at school, to when Alex moves to America where he meets Suki's character Bethany. And, obviously, there's a lot of heartache and missed romantic opportunity in-between. Think One Day, but younger.
The movie hasn't got an official release date yet, but here's the trailer to keep you going for now...
