Justin Bieber's new movie has overtaken Michael Jackson's documentary 'This Is It' as the most successful concert-themed film in US history.

The 17-year-old singer's 'Justin Bieber: Never Say Never 3-D' has already surpassed the deceased King of Pop's posthumous release, earning $72.2 million in the US since it was released in February, compared to Michael's $72.1 million, according to The Hollywood Reporter.

However, it has not beaten the worldwide record - with 'This Is It' earning $189.1 million overseas compared to just $10.8 million for Justin.

It is believed the decision to release a director's cut of the movie - including 40 minutes of extra footage - for a limited period in the US and Canada helped to increase repeat ticket sales and profits in North America.

Director Jon M. Chu said: "I realised I had an embarrassment of riches when I was I in the cutting room. This cut allows me to retain some of the best scenes from the original movie, while incorporating previously unseen footage and new material I shot during our extensive promotional tour on behalf of the movie. Justin's dedication to his fan base is unwavering and I was inspired as a filmmaker to attempt to provide them a unique experience that showed even more of his world."

Adam Goodman, President of Paramount Film Group, added: "It is a testament to the professionalism and tenacity of Jon and the production team for turning around this new version of 'Justin Bieber: Never Say Never 3D' director's fan cut in only a few months, giving fans an even deeper look into Justin's life."
