Teenage Mutant Ninja Turtles 2 opens in first place in America

Updated: 

Teenage Mutant Ninja Turtles 2 has topped the US box office, although it seems turtle power isn't as strong the second time around.

Out Of The Shadows, starring Megan Fox and Will Arnett, took just $35.3 million (£24.3 million) -- close to half of what the first film opened to in 2014.

It is the latest in a string of underwhelming openings for sequels this summer, including X-Men: Apocalypse, which fell a hefty 66% in its second weekend in cinemas, earning $22.3 million (£15.3 million) for a second place finish.

On the brighter side, the romantic tearjerker Me Before You proved again the might of the female audience.

The film - which stars Emilia Clarke and Sam Claflin - opened higher than expected with $18.3 million (£12.6 million), putting it squarely in third place.
