The hit period drama, penned by Lord Julian Fellowes, will be returning to UTV in the autumn.
In the meantime, some photos of the cast have been revealed to keep fans eagerly anticipating what will be the show's fifth series.
But the more eagle-eyed among you will notice one peculiar addition to the 1920s-era styling - a plastic bottle lurking in the background, despite not being first used until the 40s.
Downton Abbey, which began back in 2010, chronicles the day-to-day lives of the aristocratic Crawley family and their servants.
Lord Fellowes has previously hinted that this series could be the last, saying: "I don't know yet if there is a season six, but it's not going to go on forever ..."
