TORONTO (AP) -- An exuberant Julia Roberts calls working on her latest film, "August: Osage County," ''the best acting experience of my life."
The actress was bubbling with enthusiasm the day after the highly anticipated adaptation of Tracy Letts' Pulitzer Prize-winning film premiered at the Toronto International Film Festival. In the film, Roberts plays the eldest daughter of a brutally honest matriarch, played by Meryl Streep.
"I've never worked so hard in my life -- and I've given birth to three children," Roberts told reporters Tuesday.
The large cast lived near the on-location set in Oklahoma, devoting themselves to capturing Letts' dialogue. The film, to be released Dec. 25, drew mixed reviews at the festival but praise for its performances.
