TORONTO - A biopic starring Shia LaBeouf as tennis great John McEnroe will open the Toronto International Film Festival.

Organizers made the announcement on Monday, noting this will be the world premiere of "Borg/McEnroe."

The film tells the story of the epic rivalry between the American tennis star and Sweden's Bjorn Borg, which came to a head at Wimbledon in 1980.

Swedish actor Sverrir Gudnason plays Borg.

Janus Metz directed and Ronnie Sandahl wrote the film, which will be the opening night gala on Sept. 7.

Last week TIFF unveiled the first slate of films for the 42nd annual celebration of cinema, which runs through Sept. 17.
