NOAH BAUMBACH’S “While We’re Young” and Ed Zwick’s “Pawn Sacrifice” will be among the world premieres at this year’s Toronto International Film Festival, one of the top movie showcases and a favored platform to unveil Oscar contenders.

    The festival Tuesday announced about 60 titles, including many of the high-profile gala presentations that will unspool at the 39th version of the event. Departing from recent practice, festival organizers did not announce the opening film and said that it would be determined closer to the event.

    “While We’re Young,” by indie darling Baumbach, stars Ben Stiller and Naomi Watts as a middle-aged couple whose lives are disrupted when a free-spirited younger couple enters the picture. “Pawn Sacrifice” stars Tobey Maguire as American chess legend Bobby Fischer locked in a world championship match in 1972 with Soviet rival Boris Spassky, played by Liev Schreiber.

    All told, nearly 300 films are expected to screen at the festival, which ranks with Cannes, Sundance, Venice, and Berlin as leading movie events.

    The festival is tightening its scheduling criteria this year to include only true world premieres during its first four days, when media and industry attention is brightest, although organizers said that was not the cause of the delay of naming the opening night film.

    “Absolutely not. We have a lot of movies to watch... and they’re not always ready on our timeline,” festival artistic director Cameron Bailey said.

    Other films announced Tuesday include the world premiere of James Marsh’s “The Theory of Everything,” which tells the story of theoretical physicist Stephen Hawking, and the international premiere of “Wild,” starring Reese Witherspoon as a recovering heroin addict who sets out on a hike up the U.S. west coast.

    “Wild” director Jean-Marc Vallee scored strong reviews at last year’s Toronto festival and eventual Oscar glory with “Dallas Buyers Club.”

    The festival will close with historical drama “A Little Chaos,” directed by “Harry Potter” actor Alan Rickman and starring Kate Winslet as a landscaper appointed to design one of the fountains at the Palace of Versailles.

    The festival will run from Sept. 4 to 14. (SD-Agencies)
