Liv Tyler has signed up to appear in 'The Ledge'.

The 'Lord Of The Rings' actress will star alongside 'Children of Men' star Charlie Hunnam, who plays the role of a young man threatening to jump off a high-rise building.

Principal photography began yesterday (08.03.10) in Baton Rouge, Louisiana.

Director Matthew Chapman is pleased with the cast and can't wait to get started on working with them.

He said: "'The Ledge' examines the different and sometimes dangerous beliefs people adopt as a means of surviving emotional trauma.

"I am thrilled with our perfect cast and look forward to shooting the film in Baton Rouge over the coming weeks."

The film's producer Michael Mailer added: "As more and more films succumb to the visual wizardry of 3-D, 'The Ledge' explores the fourth dimension: the interior life of tortured souls hovering over the precipice of emotional nullity.

"This film is the reason why I became an independent filmmaker and why I continue to suffer in the trenches of independent filmmaking."

Also starring in the film is 'Iron Man' actor Terrence Howard, who plays the role of a policeman attempting to stop Hunnam from jumping off the building.

A release date has yet to be confirmed for the suspense thriller.
