Reese Witherspoon isnt quite sure how to categorize her next big-screen venture.

I noticed women were feeling comfortable getting divorced earlier in life, and I wanted to explore that trend.

Witherspoon plays Alice, a 40-year-old mother of two who moves home to L.A. after her marriage falls apart.

Somehow she finds herself boarding three aspiring filmmaker brothers in her guesthouse.

Together the three of them make the perfect man, laughs Meyers-Shyer.

Its kind of beautiful to see a May-December romance the other way around, Witherspoon says.

Its good to put that out there and challenge social arrays.

The older-woman-younger-man romance isnt the only love story in the movie.

Theres a great love of cinema present in the film, says Witherspoon.

Hallie is very respectful of the real craftsmanship and the sincerity of peoples artistry.

For Meyers-Shyers part, injecting the warm, sumptuous glow of old Hollywood was entirely intentional.

I wanted it to feel like a place you wanted to be.

Hollywood is really the heart of Los Angeles and its based around an art form.

Casting Pico Alexanders part was really tough, says the writer-director.

Thats what makes it a modern romantic comedy, says Witherspoon, finally giving in to that label.
