Hugh Bonneville and Damian Lewis are up against each other for drama acting honours at this year's Emmys.
The pair, in nominations announced in the US, are in the running for the best actor in a TV drama series category, and face Oscar-winning star Kevin Spacey for his role in House Of Cards.
Hugh's Downton Abbey colleague Michelle Dockery is up for the equivalent best actress prize.
House Of Cards has achieved a notable first by becoming the first programme, which has not been screened on TV, to be recognised by the awards. The series - a revamp of the BBC's political thriller - was shown by online streaming service Netflix.
Leading the tally of nominations was American Horror Story: Asylum with 17, followed by Game of Thrones with 16, while the celebrated Liberace film Behind the Candelabra - starring Michael Douglas and Matt Damon - landed 15.
Downton and Homeland also go up against each other for the best drama series title, along with House Of Cards, Game Of Thrones, Breaking Bad and Mad Men.
Another Downton star Jim Carter earns a place on the shortlist for supporting actor in a drama series, while Dame Maggie Smith from the same period drama series is up for the best supporting actress.
The Primetime Emmy Awards take place at the Nokia Theatre in Los Angeles on September 22.
