Lady Bird follows a stubbornly willful high school student, Christine 'Lady Bird' McPherson (Saoirse Ronan) who wants to go to college in New York to flee her domineering mother, played by Laurie Metcalf.

"I wrote the script to Lady Bird, and it really came out of a desire to make a project about home—like, what the meaning of home is, and place, " the film's director and writer Greta Gerwig recently told Deadline Hollywood.

"I knew Sacramento very well obviously, growing up there, and I felt like the right way to tell a story of a place was through a person who’s about to leave it. I wanted to direct for a long time, but I believed I needed a lot of experience on film sets, and I didn’t go to film school, so the way I got that was through acting and co-writing and producing. Once I had accumulated about 10 years, I thought it was enough."

She loved working with Ronan and Metcalf, "and I loved working with my DP, I loved working with my crew. There was no part of it that felt unnatural to me."

Gerwig co-directed Nights and Weekends, which appeared in 2008, but Lady Bird is her first film directed on her own. She also wrote the script for Lady Bird, "and it really came out of a desire to make a project about home—like, what the meaning of home is, and place.

"I knew Sacramento very well obviously, growing up there, and I felt like the right way to tell a story of a place was through a person who’s about to leave it."

Gerwig collaborated with film-maker Noah Baumbach in the writing of the quirkily appealing Mistress America and Frances Ha. She played female lead in both films, receiving widespread critical acclaim for her idiosyncratic performances. More recently, she was seen in the excellent Maggie's Plan

The film is due for November release in North America, but no Irish date has yet been scheduled.
