So far, 2015 has had its share of box office hits -- "Jurassic World," "Avengers: Age of Ultron" and "Furious 7" among them -- but a number of films have struggled. "Our Brand Is Crisis" had the worst nationwide start of star Sandra Bullock's career. Click through for more films that haven't lived up to expectations.

"Burnt," starring Bradley Cooper as a struggling chef, opened with a paltry $5 million.

"Truth" dramatizes the scandal surrounding CBS News in 2004 that ultimately led to Dan Rather stepping down. Early buzz made this look like a contender for Best Actress for Cate Blanchett, but that may be hampered by the fact that audiences don't seem particularly interested in revisiting this story, based on the abysmal box office.

Critics have raved about the biopic of the Apple co-founder, but "Steve Jobs" unexpectedly short-circuited at the box office.

"Jem and the Holograms" had a poorly received trailer, and the buzz never got better. Its opening weekend was nothing short of disastrous.

Critics blasted the wartime comedy "Rock the Kasbah," and audiences stayed away in droves, making it one of Bill Murray's least successful movies.

Vin Diesel as "The Last Witch Hunter" didn't attract much of an audience. There's always the next "Fast and Furious."

The big budget prequel "Pan" starring Hugh Jackman was a critical and commercial failure on an epic scale. (Attempts to reboot "Peter Pan" have rarely worked.)

Critical buzz could not save the Gothic horror film "Crimson Peak" from tanking in theaters.

"Shaun the Sheep" was adorable and critically beloved and had nonverbal characters that should have appealed to kids. Unfortunately, it was no "Minions," and families didn't bother with it.

The same October week that Robert Zemeckis' classic "Back to the Future" was being celebrated, his latest, the biographical "The Walk," was crashing and burning.

People just weren't interested in a second journey through time in "Hot Tub Time Machine 2."

Zac Efron's movie about DJs, "We Are Your Friends," really took the cake among box office bombs in 2015. It ranks as the third worst movie debut of all time.

Fox's reboot of "Fantastic Four" suffered from bad reviews and a dispute between the director and 20th Century Fox that went public. It lost its first weekend to "Mission Impossible: Rogue Nation."

"Entourage," which opened June 5, had a relatively low budget ($30 million) but got off to a poor start, taking in $10.4 million its first weekend.

Cameron Crowe's "Aloha," starring Bradley Cooper and Rachel McAdams, got terrible reviews and has grossed just $16 million on a $37 million budget.

One of the year's biggest bombs is probably the Wachowskis' "Jupiter Ascending," which cost upwards of $175 million to make and grossed less than $50 million domestically. Overseas, it did better, however, with more than $134 million in international grosses.

"Mortdecai," starring Johnny Depp, was dumped into the ditch of January and lived down to expectations, grossing about $7.7 million domestically and another $22.7 million overseas on a budget of about $60 million. The reviews were also dismal, though one critic compared it to "Hudson Hawk" with some approval.

It's been a rough few years for Vince Vaughn, who hasn't had a film break the $100 million barrier since "Couples Retreat" in 2009. His latest, "Unfinished Business," took in less than $15 million worldwide on a budget of about $35 million.

According to a Reuters story, George Lucas had been working on and off on "Strange Magic" for 15 years. But the animated film, based on "A Midsummer Night's Dream," wasn't magical at the box office. According to Box Office Mojo, it had one of the 10 worst wide openings in history and made just $12.5 million overall.

"Blackhat," starring Chris Hemsworth, was a misfire from director Michael Mann. The film was budgeted at $70 million and made just $17.8 million worldwide.

The cast of "Seventh Son" included Jeff Bridges and Julianne Moore, but the film, which also starred Ben Barnes (pictured), made just $17.2 million domestically on its $95 million budget. Overseas, things went better, as the film pulled in about $93.4 million.

"Chappie," from "District 9" director Neill Blomkamp, was another picture that fell short in the U.S. but had better luck overseas. Domestically, the $49 million film earned $31.6 million; overseas, it did more than double that amount, earning $70.5 million.
