Unfinished Business is a 2015 American comedy film directed by Ken Scott and written by Steven Conrad.

The film stars Vince Vaughn, Tom Wilkinson, Dave Franco, Sienna Miller, Nick Frost, and James Marsden.

Dan Trunkman decides to leave Dynamic Systems and start his own business in the metal swarf-selling field after a pay dispute with his boss, Chuck Portnoy.

In a Dunkin' Donuts, Dan gets a message to go on a business trip to Portland to meet with investors Jim Spinch and Bill Whilmsley.

Dan starts to lose faith in the team, as Tim is more concerned about finding a woman to make love with due to an unhappy marriage, and Mike never attended college while possibly being autistic.

After not smoking but listening to everyone, especially Mike, Dan goes out to buy "Straight Up Teal" eyeshadow and speak with his wife, his daughter, who reveals she beat up the other child for calling Paul names like "double stuff".

On February 1, 2015, an advertisement for the film was released during Super Bowl XLIX that showed a montage of scenes set to the song "Like a Boss".

This was the lowest opening of Vince Vaughn's career, the previous unfortunate box office low being $7 million by 2013's Delivery Man.

The site's critical consensus reads, "Unfocused and unfunny, Unfinished Business lives down to its title with a slipshod screenplay and poorly directed performances that would have been better left unreleased.

[15] Joe Neumaier of the New York Daily News wrote: "Unfinished Business squanders almost every opportunity provided by its potentially funny premise.

"[16] Robbie Collin of The Daily Telegraph gave the film 1 star out of 5, and said "Mawkishness, gay panic, and lazy jokes make Vince Vaughn's workplace comedy considerably less fun than work itself.

"[17] Brad Wheeler of the Toronto Globe and Mail wrote: "Not without charm, Unfinished Business mixes the cute with the raunchy.

"[18] Michael O'Sullivan of The Washington Post wrote: "While by no means a masterpiece, the comedy, by Canadian director Ken Scott, is a careful calibration of crass gags and genuine sentiment that succeeds more often than it fails.
