Not for the first time, Amy Winehouse is breaking chart records. Kapadia ’s critically acclaimed documentary chronicling the life and death of the late British singer, this weekend had the most successful debut of any U.K. documentary ever. The film – which bowed in Cannes to high praise and has since screened at the Edinburgh Film Festival and in Glastonbury – scored just north of $800,000, giving it the biggest opening for a homegrown doc in Britain and also the second-biggest doc opening ever in the country (with the exception of concert films) after Michael Moore’s 2004 hit Fahrenheit 9/11.
