David Dunn is a fictional superhero and protagonist in M. Night Shyamalan's Unbreakable film series, portrayed by American actor Bruce Willis.

When M. Night Shyamalan conceived the idea for Unbreakable, the outline had a comic book's traditional three-part structure: the superhero's "birth," his struggles against general evil-doers, and the hero's ultimate battle against the "archenemy."

He has nigh-invulnerability that renders him immune to disease and injuries, including traumas and shocks that would kill a normal human.

He has demonstrated the ability to discover actions a person committed in the past (such as Price's sabotage of the train and the unnamed murderer's crimes) as well as potential/planned acts of violence (learning a man smuggled a gun into the sports stadium).

David Dunn was born in Philadelphia and became a football player during college, before being caught in a car accident with his girlfriend Audrey.

This grabs the attention of comic book art gallery owner Elijah Price, who contacts David, taunting him, convincing him he has unique superhuman abilities.

He attempts to deny it by recalling a past drowning incident, but Elijah speculates that water is David's weakness.

He shakes hands with Elijah, discovering that he caused numerous "accidents" that have killed countless people in his search for a superhero.

One of Staple's men walks over to David and drags him over to a nearby pothole filled with water after the tank exploded.

Joseph is eventually sent the security footage of the brawl between David and Kevin at the institution, which Casey Cooke and Elijah's mother also receive.

Critic Roger Ebert believed that Willis' "subtle acting" was positively different from the actor's usual work in "brainless action movies.

"[2] Quentin Tarantino, who directed Willis in Pulp Fiction, also praised his performance in Unbreakable, saying he considers it his best work.
