(Cover) - EN Showbiz - Britain's Duke and Duchess of Cambridge have the ability to "grab headlines" wherever they go, says Steven Spielberg.

The royal couple attended the UK premiere of Steven's latest film War Horse on Sunday night at London's Leicester Square.

Steven was delighted that the royals came to the event. The legendary film director thinks the pair leave other Hollywood types in the shade.

"I have had the honour of attending a number of royal premieres throughout the 70s, 80s and 90s, but it was so wonderful being with the royal future of England. Both William and Catherine are extremely popular in America," he gushed in an interview with British newspaper The Sun.

"They can always grab the headlines away from Hollywood and [US President] Barack Obama."

The red carpet event was held in aid of the Foundation of Prince William and Prince Harry - which recognises the welfare of those who serve their country in the British Armed Forces

The foundation works with the Forces in Mind Trust to help former military personnel adjust to life outside of the forces.

The premiere is expected to raise approximately 300,000 for the charity. (C) Cover Media
