Once is a 2007 Irish romantic musical drama film written and directed by John Carney. The film stars Glen Hansard and Marketa Irglova as two struggling musicians in Dublin, Ireland. Hansard and Irglova had previously performed music as the Swell Season, and composed and performed the film's original songs. Once spent years in development with the Irish Film Board and was made for a budget of EUR112,000.
A rough cut of the film was previewed on 15 July 2006 at the Galway Film Fleadh, but the film was subsequently turned down by several prestigious European film festivals. However, once finished, it secured spots at the 2007 Sundance Film Festival on 20 January 2007 and the Dublin Film Festival in February 2007, and received the audience awards at both events.  The film was first released on cinema in Ireland on 23 March 2007, followed by a limited release in the United States on 16 May 2007. After its second weekend in release in the United States and Canada, the film topped the 23 May 2007 indieWIRE box office chart with nearly $31,000 average per location. As of 28 March 2009, Once has grossed nearly $9.5 million in North America and over $20 million worldwide. After 2007's box office success and critical acclaim, it won the Independent Spirit Award for Best Foreign Film. Steven Spielberg was quoted as saying "A little movie called Once gave me enough inspiration to last the rest of the year". When informed of Spielberg's comments, director John Carney told Sky News, "in the end of the day, he's just a guy with a beard". At the time of this interview, Carney himself was also wearing a beard.  The song "Falling Slowly" won the 2007 Academy Award for Best Original Song. The nomination's eligibility for the Oscar was initially questioned, as versions of the song had been released on The Cost and The Swell Season albums, but this was resolved before the voting for the award took place. The AMPAS music committee satisfied themselves that the song had indeed been written for the film and determined that, in the course of the film's protracted production, the composers had "played the song in some venues that were deemed inconsequential enough to not change the song's eligibility".

When was the film released?

first released on cinema in Ireland on 23 March 2007,



Answer the question at the end by quoting:

Yen was born in Guangzhou, China. His mother, Bow-sim Mark, is a Fu Style Wudangquan (internal martial arts) and Tai Chi grandmaster, while his father, Klyster Yen (Zhen Yun Long ), is a newspaper editor. When he was two years old, his family moved to Hong Kong and then to Boston when he was 11. His younger sister, Chris Yen, is also a martial artist and actress, and appeared in the 2007 film Adventures of Johnny Tao: Rock Around the Dragon.
Yen describes himself as a mixed martial artist. He learned Tai Chi from a young age under his mother's tutelage. He then wanted to learn Taekwondo in his teenage years, earning a 6th Dan in the process. At the time, the Beijing Wushu Team had a scout in the United States and invited Yen over to Beijing, China, where he began training at the Beijing Sports Institute, the same facility where champion-turned-actor Jet Li trained; this is where the two of them crossed paths for the first time.  Upon his return to the United States, Yen won gold medals in various wushu competitions.  Yen later went on to discover and seek knowledge on other martial arts styles; he would later obtain black and purple belts from judo and Brazilian Jiu-Jitsu, respectively, and went on to study the art of Parkour, Wrestling, Muay Thai, Kickboxing and Boxing under various trainers. His exposure to mixed martial arts (MMA) was heightened when he went back to the United States from 2000 to 2003. While making his Hollywood debut, he also took time off to learn the various martial arts forms. Yen's progress was evident when he returned to Asia, where he implemented his newfound knowledge of MMA, showcased in films such as SPL: Sha Po Lang (2005), Flash Point (2007), and Special ID (2013).  Near the end of 2007, Yen added a new martial arts system to his arsenal. He was offered the role of Wing Chun grandmaster and mentor of film star Bruce Lee, Ip Man, in a 2008 film named after the grandmaster. He worked hard and studied Wing Chun under Ip Man's eldest son, Ip Chun, for 9 months before tackling the role. Ip Chun has since praised Yen for his effort, his skills as a martial artist, and his ability to grasp the full concept of Wing Chun much faster than anyone else he has taught.  Yen believes that combining many martial arts together will produce the most effective and harmonious style. Yen has said, "When you watch my films, you're feeling my heart." He believes in practical combat, and in his opinion, MMA is the most authentic type of practical combat. He has mentioned that he would have competed in the Ultimate Fighting Championship if he did not have a recurring shoulder injury.
