Two high-profile directorial debuts are among five films added to the Toronto International Film Festival's September Special Presentations line-up.

Pulitzer Prize winner David Auburn (Proof, The Lake House) has directed his own screenplay with The Girl In The Park.

The film features Sigourney Weaver as long-suffering mother who encounters a troubled teenager and suspects the youngster may be her daughter who disappeared as an infant 15 years earlier. QED is handling sales.

Actress Helen Hunt makes her directorial debut with Killer Films' adaptation of Then She Found Me, the eponymous debut novel by Elinor Lipman.

Hunt directs herself as April, a teacher nearing 40 whose calm world is turned upside down when her husband (Matthew Broderick) leaves her, her adoptive mother dies and a stranger (Bette Midler) declares herself April's biological mother. Colin Firth also stars.

The other titles announced include:

Romulus, My Father, the feature debut of Australian actor Richard Roxburgh (Moulin Rouge, Van Helsing), starring Eric Bana and Franka Potente. It was released in Australia in May. Arclight is handling sales.

John Sayles' period title The Honeydripper, starring Danny Glover as a down-on-his-luck bar owner who hires a guitar-playing drifter, Gary Clark Jr., to bring in customers and unwittingly provides the crucible for the transition of the blues into rock'n'roll. The project was first pitched at Rotterdam 's CineMart in 2005.

Lars And The Real Girl, from Craig Gillespie and written by Six Feet Under writer Nancy Oliver, features Ryan Gosling as a hapless small-town wage slave who meets a made-to-order life-size doll. Emily Mortimer, Paul Schneider, Kelli Garner and Patricia Clarkson round out the cast. Kimmel International sold several territories out of Cannes in 2006.

Despite announcing the world premiere of Jeremy Podeswa's Fugitive Pieces earlier this year, TIFF declined to indicate the premiere status of any of the announced titles (although clearly Romulus, My Father will be an international premiere at best). A TIFF spokesperson said the festival would wait until the end of August before confirmation.
