Once (film) - Production

Production

Neither of the two leads is a trained or experienced actor; Hansard and Irglová are both professional musicians. Director Carney, former bassist for Hansard's band The Frames, had asked his long-time friend to share busker anecdotes and compose songs for the film, but had intended the male lead to be played by actor Cillian Murphy, who was an almost-signed rock musician before turning to acting. Murphy was also going to be one of the film's producers. But Murphy declined the prospect of acting opposite non-actor Irglová (then 17 years old) and also felt that he hadn't the vocal capabilities to belt out Hansard's octave-leaping songs, so he pulled out, as did the film's other producers along with their financial resources. Carney then turned to songwriter Hansard, who'd previously done only one acting job, a supporting role as guitarist Outspan Foster in the 1991 ensemble film The Commitments, the story of a Dublin soul music cover band. Hansard was initially reluctant, fearing that he wouldn't be able to pull it off, but after stipulating that he had to be fully involved in the filmmaking process and that it be low-budget and intimate, he agreed.

Produced on a shoestring, about 75% of the budget was funded by Bord Scannán na hÉireann (The Irish Film Board), plus some of Carney's own money. The director gave his salary to the two stars, and promised a share of the back-end for everyone if the film was a success. Shot with a skeleton crew on a 17-day shoot, the filmmakers saved money by using natural light and shooting at friends' houses. The musical party scene was filmed in Hansard's own flat, with his personal friends playing the partygoers/musicians—his mother, Catherine Hansard, is briefly featured singing solo. The Dublin street scenes were recorded without permits and with a long lens so that many passersby didn't even realize that a film was being made. The long lens also helped the non-professional actors relax and forget about the camera, and some of the dialogue ended up being improvised.

During the shoot, Carney had predicted a romance, calling Hansard and Irglová his Bogart and Bacall. Hansard and Irglová did become a couple in real life, getting together while on a promotional tour across North America, and living together in Dublin, in Hansard's flat. Entertainment Weekly reported:

The chemistry between (the) two leads ... was easy to produce during the January 2006 shoot in Dublin. "I had been falling in love with her for a long time, but I kept telling myself she's just a kid," says Hansard, 37, who has known his 19-year-old costar for the past six years. (The two are now dating.) "There was definitely the feeling we were documenting something precious and private."

Subsequently, Hansard indicated that that they were no longer a romantic couple. He said, "Of course, we fell into each other's arms. It was a very necessary part of our friendship but I think we both concluded that that wasn't what we really wanted to do. So we're not together now. We are just really good friends."

Yet Hansard and Irglová were quite happy with the unrequited ending for their onscreen characters. In an interview, Hansard states that "Had the US distributor changed the end and made us kiss, I wouldn't be interested in coming and promoting it, at all." Hansard says that ad-libbing produced the moment where Irglova's character tells the Guy in unsubtitled Czech, "No, I love you", but when it was shot, he didn't know what she'd said, just like his character.

Both Hansard and Irglova give the impression in interviews that they are unlikely to pursue further acting. Irglova has spoken about being nervous in front of a crew, saying "I don't think I would be a good actress, overall", and Hansard generally refers to the movie as a one-off, talking of "moving on... living a different life".

As a result of the film, Hansard and Irglová have been releasing music and touring together as The Swell Season.

Glen Hansard and Markéta Irglová reprised their roles in The Simpsons episode "In the Name of the Grandfather".
