Actress Margot Robbie has been tapped to round out the voice cast for the forthcoming Peter Rabbit movie.

The Suicide Squad star is in final negotiations to join Into the Woods actor and TV host James Corden, who will provide the vocals for the titular character in the film, based on children's author and illustrator Beatrix Potter's beloved tale about a mischievous bunny.

Specific details about Robbie's role have yet to be released, but if she signs on, she will follow in the footsteps of Domhnall Gleeson, her co-star in another children's literature-related project, a biopic of Winnie-the-Pooh author A. A. Milne, in which the Irish actor portrays the late English writer and Margot his wife, Daphne.

Gleeson was cast as Mr. McGregor, the disgruntled farmer who tries to catch and cook Peter and his furry family members, last week (ends21Oct16), days after his Star Wars: The Force Awakens castmate, Daisy Ridley, boarded the project, too.

Rose Byrne will tackle the female lead as Bea, while The Night Manager actress Elizabeth Debicki will also feature in Peter Rabbit.

Byrne's Annie remake director Will Gluck will take charge of the project. He will team up with animators at Australia's Animal Logic, the production studio behind The LEGO Movie, to bring the characters to life onscreen.

Filming is set to begin in January (17) in Sydney, Australia and the movie is scheduled to hit the big screen in April, 2018.

It'll be a busy few months for Robbie - the Australian beauty has also lined up a Harley Quinn spin-off film, in which she will reprise her role as the Suicide Squad member, while she is preparing to portray disgraced figure skater Tonya Harding in I, Tonya, too.
