The Hot Docs Canadian International Documentary Festival began in Toronto last night with the Canadian premiere of Sundance hit “Al Weiwei: Never Sorry.” The screening, at the festival’s newly renovated hub The Bloor Cinema, kicks off 10 days and nights of North America’s largest documentary festival.

While plenty of breakout films from Sundance and other major festivals will certainly be a big part of the festival, Hot Docs also offers plenty of opportunity for discovery. So here’s 10 films you might not have heard of yet with buzz heading into Hot Docs. Check them out over the next 10 days in Toronto or — quite likely — at many doc film festivals to come:

Affair Of The Heart (directed by Sylvia Caminer)
A Rick Springfield documentary! Sylvia Caminer’s “Affair of the Heart” takes on the “Jesse’s Girl” singer, checking in with the now sixtysomething Springfield (who still does 100+ concerts a year) and his rabid fans. And yep, Springfield will indeed attend the film’s premiere screening on April 29th.
