Dan Stevens broke our hearts when he left "Downton Abbey" after Season 3, and now he might be toying with them.

The actor got fans all stirred up with an Instagram post on Sunday -- and understandably so. The image he shared is of him with his former "Downton" co-stars Michelle Dockery and Allen Leech. Not only that, he captioned it, "Should Matthew have a mustache for the #DowntonAbbeyMovie...? Vote below..."



The idea of Stevens coming back is pretty wild considering that his character, Matthew Crawley, died in a car accident and "Downton Abbey" isn't the kind of show that resurrects deceased characters. Fans let him know it, too. Although some responded with enthusiasm, there was a lot of skepticism in the post's comments. One person even wrote, "with all the love and kindness in [their] heart," that Matthew should "STAY DEAD."

It is, however, possible that "Downton" creator Julian Fellowes could find a graceful way to include Stevens without the story going off the rails (or the road -- RIP, Matthew). There could be a flashback, or maybe even a dream sequence. Done well, it would be nice chance to see the whole cast together once again.

So far, we don't know whether Stevens was serious or just having fun while hanging out with his former colleagues. The specifics of the cast and plot have remained a mystery since the official "Downton Abbey" movie announcement came last month.

Production on the film begins this summer.
