Her, a futuristic and highly-unconventional love story that was written and directed by Spike Jonze, had its world premiere on Saturday night as the Closing Night Gala screening of the 51st New York Film Festival at Lincoln Center’s Alice Tully Hall.

The film, which will be released by Warner Bros. on Dec. 18, stars Joaquin Phoenix as a man who rebounds from a divorce (from Rooney Mara) by dating his advanced operating system (voiced by Scarlett Johansson). Check pictures from premiere and today’s press conference in our gallery:
