LOS ANGELES- Reuters/Metro- The Will Smith blockbuster After Earth is on course to be the box office bomb of the summer after being slammed by US critics and underperforming in cinemas on its opening day.

According to official figures the sci-fi epic, directed by M Night Shyamalan, took between nine and $10m at the US box office - only a fraction of its predicted gross.

By contrast, Smith’s 2012 summer blockbuster Men In Black 3 scored an opening weekend of $55m when it was released on Memorial Day last May.

The actor’s other recent efforts have also started strongly, with Hancock opening to $62.6m in 2008 and I Am Legend scoring an opening weekend of $77.2m in 2007. However After Earth - in which Smith shares the screen with his son Jaden - has not been helped by almost universally negative reviews.

Will Smith may be one of Hollywood’s most bankable action stars, but his new film, “After Earth,” in which he stars with his 14-year-old son Jaden, has opened to cold reviews from critics and faces stiff competition in a busy box office weekend.

“After Earth” is a futuristic post-apocalyptic tale of a father and his teenage son in which the young boy must embark on a life-saving mission.

Sony Pictures Entertainment, a division of Sony Corp., spent about $130 million to produce the movie, making it one of the studio’s biggest summer releases.

The story is centered on the father-son relationship and the dynamic of a father passing the mantle to his son is mirrored both on screen and off, as the younger Smith leads the action.

Will Smith, 44, who wrote the initial story and was the executive producer of the film, said the project gave him valuable time to spend with his son, with whom he first starred in the 2006 family drama, “The Pursuit of Happyness.”

“Filmmaking and entertainment is our family business,” Smith said at a recent news conference. “So, it really gave us an opportunity for the last year to spend ten or twelve hours a day together, every day. And for me it’s just the best way, for me at least, to parent.”

Jaden Smith bears a strong resemblance to his famous father and won over most critics as the lead in 2010’s reboot of “The Karate Kid.” However, he has not been received as warmly for his performance as ranger Kitai Raige in “After Earth.”

Variety’s Scott Foundas said both father and son failed to meet expectations. “Senior Smith gives one of the least substantive performances of his career, while the undeniably charismatic Jaden toggles between ... paralyzing fear and simmering rage.”

Manohla Dargis wrote in the New York Times that the younger Smith was “a pretty teenager with jumpy eyebrows whose character remains an insufferable brat.” Rolling Stone’s Peter Travers slammed the script as “an unholy mess of platitudes and posturing.” He gave the film one out of five stars, saying “It’s not a good sign when you sit there thinking one thing - Make. It. Stop.”

“After Earth” scored just 32 out of 100 on Metacritic.com, which compiles ratings based on critics’ reviews. Only 13 percent of critics recommended the movie in reviews collected on the Rotten Tomatoes website. This is despite the fact that the film was directed by M. Night Shayamalan, who scored a huge hit with the 1999 suspense drama

“The Sixth Sense,” which grossed more than $672 million at the worldwide box office. Shayamalan was less successful though with 2006’s “Lady in the Water” and 2010’s “The Last Airbender.” Box office forecasters predict “After Earth” will make $35- $40 million in US and Canadian ticket sales from Friday through Sunday.

The film opened on Thursday and took in $1 million at US and Canadian theaters, behind Lions Gate Entertainment’s comedy heist caper “Now You See Me,” which earned $1.5 million.
