Director Roland Emmerich's gay rights drama Stonewall will have its world premiere at the 40th edition of the Toronto International Film Festival (TIFF), which runs September 10-20.

Stonewall tells a fictional story about a young man's political awakening set against the backdrop of the early days of the modern gay rights movement. Historians often credit the June 28, 1969 police raid of the Stonewall Inn in Greenwich Village as a major flashpoint for the movement. While such raids at the time were common at gay bars, patrons on that night, many of whom were drag queens, resisted arrest.

The film arrives at a pivotal moment for the movement, which is moving from fighting for marriage equality to protecting the right from opponents who wish to dilute it.

The film stars Jeremy Irvine, Jonny Beauchamp, Jonathan Rhys Meyers and Ron Perlman.

Stonewall opens on September 25.

At a press conference on Tuesday, TIFF announced that Demolition, starring Jake Gyllenhaal, Naomi Watts and Chris Cooper, will open this year's festival.
