Actor Peter Facinelli is developing a movie about American spy Nathan Hale.

The Twilight star has acquired the film rights to M. William Phelps' Nathan Hale: The Life and Death of America's First Spy, which centres on the undercover agent who was executed in 1776 at the age of 21 after British forces discovered he was a soldier for the Continental Army in the Revolutionary War.

Facinelli says, "I am excited to bring the story of Nathan Hale to life, a man who sacrificed everything for what he believed in."

The film was originally slated to be developed by producers at Warner Bros. in 2007, but the project fell through, according to
