What isThe Idea Of Youabout?

The story is centred on a 39-year-old French-born art gallerist named Solène Marchand, who is a divorced mother of one. In an unexpected turn of events, Solène meets and begins a relationship with Hayes Campbell, the 24-year-old dreamy British frontman of her teen daughter’s favourite boy band, August Moon.

The movie adaptation sticks very close to the original plot, as it chronicles Solène and Hayes' love story as they navigate being two people from very different worlds who are falling passionately in love, all while the world is watching their every move and Solene's own daughter is wrapped up in her fandom of her mother's new boyfriend.

Robinne Lee said that the real hook of the story is Solène falling in love with life in her 40s, just as much as she falls in love with Hayes.

"It was supposed to be a story about a woman approaching 40 and reclaiming her sexuality and rediscovering herself," the author toldVogue. "Just at the point that society traditionally writes women off as desirable and viable and whole."

There have been some changes to the story during the journey of adapting the book into a movie, so even if you've devoured the novel already you'll still in for some big surprises when it comes time to sit down and watch the film.

Speaking at the film's world premiere at SXSW, Anne shared why she decided to take on the role, explaining that she feltThe Idea OfYouwasabout a woman who changes her life in her 40s.

"For some reason, we talk about coming-of-age stories as being something that happens to you in the earliest part of your life, and I don’t know about you, but I feel like I keep blooming," she said at the premiere "I don’t want to be pigeonholed and don’t want to be placed in a box of what type of films I have to be making because of my age, gender, and because I won an Oscar. I want to have fun, dammit. It speaks to me."

English actor Nicholas Galitzine first caught our eye in the romantic dramaPurple Heartsand made us laugh out loud with his role in the comedyBottomsbut it was his role as Prince Henry inRed, White & Royal Bluethat truly made audiences fall in love with him and cemented him as a leading man.
