Cadbury's 2015 Christmas advert will feature an advent calendar formed of 24 purple trucks.
The chocolate brand plans to deliver joy to the nation over the festive season with its biggest Christmas campaign ever.
Each of the 24 trucks will represent a different door of the advent calendar and the advert will be brought to life when they depart to a different location everyday in the ultimate countdown.
Marketing manager Claire Low said: "Through this ad, we wanted to capture the huge anticipation felt by consumers during the Christmas countdown. Cadbury has a well-loved place in family homes during the festive period, and has been bringing joy to the countdown with its advent calendars for over 50 years. Inspired by this, we have created the ultimate advent calendar to deliver joy in a way that only Cadbury can this Christmas."
The advert is set to premiere during 'The X Factor' tomorrow (07.11.15).
