Funnyman Vince Vaughn is probably wishing that his Unfinished Business had stayed incomplete, after the comedy was savaged by critics. But to add insult to injury, now it seems audiences have also failed to see the funny side of his latest outing, leaving the actor on track for his worst opening ever for a major release.

unfinished businessUnfinished Business has bombed at the box office.

According to The Hollywood Reporter the comedy may only take $5 million on its opening weekend, leaving it finishing in eighth place at the box office. The low number would make it Vaughn's worst ever opening for a major release and certainly the worst for a comedy.

In 1998 Vaughn did star in drama Return to Paradise which only opened to $2.5 million, but it only went out in 965 theatres as opposed to Unfinished Business’ 2,777. But the actor hasn’t exactly been on a hot run at the box office as of late anyway, in 2013 Delivery Man and The Internship both failed to make waves while the latter, which was co-written by Vaughn, was also panned by critics.

The reception to Unfinished Business from the critics has been on the whole very negative, with the film earning an embarrassing 13% rotten rating on Rotten Tomatoes.

According to the consensus the film is “unfocused and unfunny” and it “lives down to its title with a slipshod screenplay and poorly directed performances that would have been better left unreleased.”

Our own Rich Cline echoed the sentiment in his review when he wrote the film was “more than just a misfire." Adding that "this attempt at a rude comedy goes so spectacularly wrong that it actually contradicts its own jokes even as it's telling them.”

But Unfinished Business aside, this weekend looks to be an unspectacular one at the box office anyway, with dystopian robot film Chappie predicted to take the top spot despite a projected opening of just $13 million.

Starring Hugh Jackman and Dev Patel the film cost $49 million to make and is directed by District 9 and Elysium’s Neill Blomkamp. If the film comes in at the low $13million number it will be a debut considerably lower than Blomkamp's previous outings.
