Donnie Yen is the Hong Kong actor and director best known for his starring role in Ip Man, but across the world he'll soon have a new claim to fame. Yen is one of the actors starring in Lucasfilm's Star Wars anthology film, Rogue One.

But he seems to have made a faux pas.

On his Instagram and Facebook accounts, Yen today posted a photo of three helmets belonging to different branches of Star Wars' villainous Empire. Less than two hours later, the photo had vanished from both accounts.

Oops.

Perhaps Yen didn't have permission to post the photo, or maybe he simply wasn't clear on the level of secrecy Lucasfilm employs for a Star Wars movie. Either way, someone from Disney or Lucasfilm obviously spoke to him, resulting in the photo's hasty deletion.

Fortunately for the rest of us, two hours was more than enough time for a handful of followers to download the pic and then post it online.

The photo shows the three helmets side-by-side on a shelf. Take a look.

The one in the middle is the instantly recognizable classic Stormtrooper helmet. On the left is something evocative of the helmets worn by the Empire's TIE Fighter pilots, though this appears to be a never-before seen variant.

It's the one on the right that really catches your eye, though. That one is something that can't be easily compared to any Imperial armor we've seen before. It has overtones of the Scout Trooper helmets used by soldiers on Endor, in Return of the Jedi. But on the other hand, the yellow coloring could indicate its use in a desert environment.

Are these all helmets that Yen's character will wear in the movie, perhaps in an undercover fashion? Are they trophies he keeps after victories? Or did Yen simply walk past these in the production offices one day and snap a quick photo?

All we know for certain about Rogue One is that its storyline is a "ground-level war movie" about the band of Rebels who stole the Death Star plans shortly before the events of A New Hope.

Felicity Jones leads the Star Wars: Rogue One cast, with Yen co-starring alongside Forest Whitaker, Mads Mikkelsen, Alan Tudyk, Ben Mendelsohn, Riz Ahmed, Diego Luna and Jiang Wen. It's rumored that Darth Vader and Grand Moff Tarkin could both make appearances. Gareth Edwards is directing a script by Gary Whitta and Chris Weitz, based on an original idea by VFX guru John Knoll.

Star Wars: Rogue One is scheduled to be in theaters on December 16, 2016.

Elsewhere in Star Wars news, Empire Magazine posted a new photo of actor Adam Driver as villain Kylo Ren from Star Wars: The Force Awakens.
