The last time you heard the names Glen Hansard and Markéta Irglová was probably in 2008, when they charmed your pants off in 'Once' and won an Oscar for Best Original Song. Since then, the onscreen duo continued their off-screen romance, broke-up, and toured the globe as The Swell Season. Now, a behind-the-scenes documentary about their love after fame and their fractured romance has arrived, fittingly titled 'The Swell Season.' Check out the first trailer for the film, which was directed by Nick August-Perna, Chris Dapkins and Carlo Mirabella-Davis.
