Unleashed (French: Danny the Dog) is a 2005 action film directed by Louis Leterrier and written by Luc Besson.

The action scenes were choreographed by Yuen Woo-ping, with the film's setting and shooting location in Glasgow, Scotland.

Bart, a vicious loan shark residing in Glasgow, uses his bodyguard, Danny, to attack non-complying customers.

As a result, he has very little knowledge on how to act as a socialized person, and the collar trick begins to fail due to its inherent limitations.

After Danny easily wins the first fight, however, Bart gets into a mishap with another mobster and is left for dead after a shooting.

Danny slowly learns to be a civilized man and abandons his violent nature, especially after Victoria removes his collar.

He also curiously develops an interest in music and begins using scattered memories to try and remember his past, particularly his mother.

Bart denies knowing her and snaps a new collar back on Danny before taking him to the fighting ring.

Danny refuses to fight, insisting he doesn't want to hurt people anymore, forcing a livid Bart to shove him into the pit.

Danny initially struggles against his four opponents but eventually defeats them all to save his own life; however, he refuses to kill them, much to Bart's chagrin.

In 2005, Virgin Records re-released the soundtrack under the title Unleashed, with two bonus tracks produced by the RZA.
