Bieber doc bombs at box office

Though it seems that the news of Justin Bieber's retirement may have been exaggerated, his career at the box office appears to be ailing.

His latest documentary 'Believe' has bombed at the US box office.

The film debuted in the US last weekend, but limped to an opening haul of only $2.2 million.

Although the documentary film was made at a cost of $5 million, and cost another $5 million to market and promote, it's so far made a fraction of the cash made by 'Never Say Never', the first Bieber film, released in 2011.

That film stormed the US box office charts, opening with a record-breaking take of $29.5 million, and scoring $73 million in all.

It made it the most successful concert movie of all time.

But it's projected that 'Believe' may only make somewhere around the $10 million mark.

It follows a similarly disappointing performance by boyband One Direction, whose documentary film 'One Direction: This Is Us', made by 'Supersize Me director Morgan Spurlock, made $28.9 million.

It also follows the strange decision by the teen singer to announce his retirement via his Twitter account on Christmas Eve.

The tweet has since been removed, with his manager Scooter Braun denying he is quitting music, rather taking a hiatus.
