Julia Roberts heads all-star romantic comedy

Jessica Biel, Ashton Kutcher and rising star Bradley Cooper are also set to star in the project.
MacLaine will play Roberts's mother, a retiree who reveals an affair to her husband while Oscar-nominee Hathaway will play an assistant at a Los Angeles talent agency dating a mailroom assistant.
The film is being produced by New Line studio, which enjoyed recent success with another ensemble romantic comedy "He's Just Not That Into You."
