16 Blocks is a 2006 American crime thriller film directed by Richard Donner and starring Bruce Willis, Mos Def, and David Morse.

It marked the final directed film for Donner during his lifetime[3][4] in addition to the last acting role for his cousin and frequent collaborator Steve Kahan.

Despite a grueling late shift the night before, his lieutenant orders him to escort a witness, Eddie Bunker, from local custody to the courthouse sixteen blocks away to testify on a police corruption case before a grand jury at 10 a.m. Bunker tries to be friendly with Mosley, telling him of his aspirations to move to Seattle and open a bakery with his sister who he has never met, but Mosley is uninterested and insists on stopping at a liquor store.

Hired assassins shoot up the escort car, and Mosley drags Bunker to his favorite bar to take shelter and call for backup.

Bunker's tenacity convinces Mosley to keep fighting, and he manages to drive the bus into an alley, temporarily blocking the police from following them.

He celebrates his birthday with Diane and other friends and is surprised to find that the cake had indeed come from Bunker, who has been successful in starting "Eddie & Jack's Good Sign Bakery" in Seattle.

[citation needed] 16 Blocks is the second film in which David Morse plays the villain to Bruce Willis as the protagonist; the first was 12 Monkeys.

The ending written for the film changed the scenario in which Frank after watching Jack get in the elevator, instructs Bobby to stand down, saying it's over.

The site's consensus reads: "Despite strong performances from Bruce Willis and Mos Def, 16 Blocks barely rises above being a shopworn entry in the buddy-action genre.

[8] Michael Atkinson of The Village Voice commented that "the clichés come thick on the ground" and called it "a small movie trying to seem epic, or a bloated monster trying to seem lean.

"[9] Peter Travers of Rolling Stone gave the film two-and-a-half out of four stars and called Willis and Mos Def "a terrific team," concluding that "Until Richard Wenk's script drives the characters into a brick wall of pukey sentiment, it's a wild ride.

"[10] Chicago Sun-Times critic Roger Ebert gave it three out of four stars and commended Mos Def for his "character performance that's completely unexpected in an action movie," while calling the film "a chase picture conducted at a velocity that is just about right for a middle-age alcoholic.
