She's a dame of the British Empire portraying a former empress of Russia, so it was natural that Helen Mirren should make a regal entrance to the premiere of her latest work.

The British actress is playing Catherine the Great in an upcoming, eponymously titled HBO miniseries about Russia's longest-ruling female leader.

The four-part show, which is due to hit screens on HBO and Sky Atlantic on Monday, October 21, follows the later years of the empress's reign and her relationship with military leader Grigory Potemkin.

Catherine was Empress of Russia from 1762 until 1796, and has been credited with creating a stronger, more powerful nation during her rule.

Ahead of her portrayal of the royal hitting screens, Mirren, 74, rocked up to the London premiere in a majestic litter.

The Oscar winner, who scored an Academy Award for her turn as HRH Elizabeth II in The Queen, made her way down the red carpet, nestled in a decadent sedan chair carried by four ornately dressed guards.

Mirren was joined on the red carpet by her Catherine the Great co-stars Kevin McNally, Gina McKee and Jason Clarke.

To complement her entrance, the star wore jewels fit for a royal and a striking, all-navy ensemble.

The wide-leg panelled trousers and a structured long-sleeve top were the work of Chalayan, the namesake label by Cypriot-Turkish fashion designer Hussein Chalayan.

The label, which has been sported by the likes of Kim Kardashian West, Sophie Turner and Rihanna, is renowned for its avant-garde approach to design, with conceptual silhouettes and use of new technology in textiles.

Mirren has previously sported a number of labels from the Mena region and beyond, turning to Elie Saab, Reem Acra and Rami Al Ali on red carpets past.
