Dan played Matthew Crawley in the show
Dan starred as leading man Matthew Crawley in the hit ITV series until he left in a very dramatic fashion at the end of the Christmas special last year.
Awkwardly Dan has gone on to star alongside Benedict, 36, in upcoming film The Fifth Estate and he admits to taking the opportunity to tease his co-star over the remarks.
‘Poor Benedict. I tease him about it every time I see him,’ Dan, 30, tells Event Magazine.
‘It’s an easy way to make him feel bad.’
Benedict, who starred in rival period drama Parade’s End, blasted Downton Abbey’s portrayal of World War I.
‘We’re living in a culture now that’s revering, or having a nostalgia trip with, the beginning of the 1900s,’ the Sherlock star told Reader’s Digest last year.
‘Although Downton traded a lot on the sentiment in the last series…but we won’t talk about that series because it was, in my opinion, f*cking atrocious.’
