Olivia Coleman speaks as 'old bat' Queen Elizabeth II in new The Crown trailer

Olivia Coleman has made her debut as the new actress playing Queen Elizabeth II in The Crown, speaking on camera as the monarch for the first time.

All major roles on The Crown have new actors for the upcoming season, Coleman taking over from Claire Foy while Tobias Menzies takes over from Matt Smith as Prince Phillip.

Coleman has already appeared on camera as Elizabeth once, for around four seconds, during the video announcing the premiere date for season three.

But the latest trailer released on Saturday morning shows her speaking as the Queen for the first time with the royal's famous upper-class accent.

It shows the Queen looking at her new royal profile, which photographers say shows Elizabeth's transition away from a young woman.

Elizabeth remarks she's become an "old bat" before the photographers say she's a "settled sovereign".

"A great many changes. Nothing one can do about it. One just has to get on with it," she says.

The Crown will be released worldwide on November 17.
