The festival, finalizing its final lineup, also booked the David Oyelowo-starrer 'Five Nights in Maine' and 'James White,' featuring Christopher Abbot and Cynthia Nixon.

Hollywood leading ladies Julianne Moore, Salma Hayek and Sarah Silverman are set to take part in onstage conversations at the Toronto Film Festival, organizers said Tuesday.

The three actresses will join Mad Men creator Matthew Weiner as part of Toronto's inaugural "In Conversation With..." sidebar to talk about their careers and latest films. Oscar winner Moore will be in Toronto with the previously announced Freeheld, which she stars in opposite Ellen Page and Michael Shannon.

Hayek, an Oscar nominee, will help launch Wayne Blair's Septembers of Shiraz in Toronto. And Silverman stars in in I Smile Back, another previously announced Toronto selection, while Weiner will be at the festival to talk about Mad Men as part of Toronto's inaugural Primetime showcase of TV dramas.

Toronto earlier chose to shake up its industry conference with Empire producer Wendy Calhoun, Oddlot Entertainment's Gigi Pritzker and Warner Bros.' Niija Kuykendall talking about "uncovering unconscious bias" when financing female-led movies.

Toronto's onstage conversation lineup was revealed as the festival finalized its 2015 edition lineup, set to consist of 289 features and 108 shorts from 71 countries. That includes 132 world premieres, 27 international bows, 97 North American premieres, and films featuring such Hollywood stars as Sandra Bullock, Keira Knightley, Naomi Watts, Robert Redford, Cate Blanchett, Susan Sarandon, Anna Kendrick and Johnny Depp.

The fest will also host Hollywood director Michael Mann in a Q&A following a 20th anniversary screening of Heat, starring Al Pacino and Robert De Niro. The latest film lineup additions by Toronto include 30 films in the Discovery program.

The festival added a first look at Maris Curran's Five Nights in Maine, starring David Oyelowo, Dianne Wiest and Rosie Perez in a drama about a young African-American man in rural Maine seeking answers from his mother-in-law after the tragic death of his wife.

There are also world bows for New Zealand actor Tammy Davis' feature directorial debut, the coming-of-ager Born to Dance and U.K. director Michael Lennox's A Patch of Fog, starring Boardwalk Empire's Stephen Graham and Conleth Hill and Ian McElhinney of Game of Thrones. Toronto also booked a Canadian debut for writer/director Josh Mond's James White, which stars Christopher Abbott and Cynthia Nixon. The Film Arcade snapped up the U.S. rights to James White after a world bow at Sundance.

Toronto festival artistic director Cameron Bailey told The Hollywood Reporter the 2015 edition's lineup aimed for a balance between star-driven movies and discovery titles by U.S. and other international auteur directors.

"The Platform program is the single biggest way for us to balance the festival, to make sure there's a strong place for independent cinema, auteur cinema and international cinema in addition to all the films that we get with big red-carpet stars in them," Bailey said about the juried Platform competition, new to Toronto this year.

The 40th edition of the Toronto Film Festival is set to run Sept. 10-20.
