Hugh Bonneville has insisted the end of Downton Abbey is still yet to be decided.
Julian Fellowes, creator of the hit ITV period drama recently said he did not know if there would be a sixth season of the show.
But Hugh told Digital Spy at the National Television Awards: "There's no plans to definitely finish the show after series five. I'm intrigued to find out what the future of the show is."
He added: "Our executive producer Gareth Neame went on record to say there are no plans to end the show after series five. He apparently said the show will run between five and 10 years, so take your pick."
The actor stars as lord of the manor Robert Crawley.
A fifth series of Downton Abbey was confirmed by ITV in November, and is expected to air later this year.
Hugh said: "I know that we start filming on February the 10th, that is literally all I know. I haven't seen scripts of anything."
Fellowes said of Downton earlier this year: "I don't know yet if there is a season six, but it's not going to go on forever."
But exec producer Neame quickly denied rumours the show was being axed, saying: "There are no plans to end the show after the fifth series. ITV commission each series on a year-by-year basis."
