Downton Abbey star Michelle Dockery dons Elizabethan costume and also appears as a 1920s flapper in an advert launched to promote UK tourism.
Dockery, who plays Lady Mary in the hit TV series, is seen in the costumes on the Giant’s Causeway on Northern Ireland’s Antrim coast.
Also appearing in the advert are actor and broadcaster Stephen Fry, actress Julie Walters and Harry Potter star Rupert Grint.
Launched by Culture Secretary Jeremy Hunt, the Holidays at Home campaign urges Britons to holiday in their own country.
To mark Olympic year, some holiday companies will be slashing 20.12% off the cost of trips. Tourists will be able to take advantage of the discount by using a dedicated website before the end of the Paralympics on September 9 to make bookings for this year and 2013.
More than three million hotel rooms are already lined up under the project, which is being backed by a range of companies including Butlins. Attractions such as the London Eye and Alton Towers are also taking part.
Mr Hunt said: “2012 is going to be a year like no other in our history with the diamond jubilee celebrations and the Olympics. With so much going on, this is the perfect time to make the most of the UK and take your holiday, long weekend or short break here.
“The 20.12% campaign has got thousands of fantastic offers to make holidaying at home affordable this year and the advert really does show off what’s great about the UK.”
James Berresford, chief executive of VisitEngland, said: “This is the largest domestic tourism campaign ever undertaken and aims to inspire UK residents to take advantage of the fantastic events taking place in the country this year.
“We have thousands of offers up and down the country which means a family can enjoy great deals on accommodation, meals and tickets to attractions at very affordable prices.”
