Bartley, who plays The Ferg on Longmire, posted a new photo on Instagram Thursday of Robert Taylor (Walt) and guest star Terry Camilleri. The actor is currently on set of the Western drama as they film their fourth season.

The photo features Taylor looking like he's giving Camilleri a massage on his shoulders.

"The incredible Terry Camilieri in his #Longmire debut! Better known as Napoleon in Bill and Teds Excellent Adventure!!!" Bartley said in the caption of the photo.

Camilleri is indeed well known as playing Emperor Napoleon I in the cult classic comedy Bill and Ted's Excellent Adventure. Other credits include The Truman Show, Gigli and Knowing.

It is unknown who Camilleri will be playing in the new season, but it looks like he and Taylor will be sharing the screen at some point.

Longmire was cancelled by A&E after three highly-rated seasons last August. However, the show had low ratings in the adults 18-49 demographic so it was canned. With fans understandably upset, they launched a big Twitter campaign to save the Western.

Netflix then swooped in in November, picking up the show for a 10-episode fourth season. The cast and crew are currently about halfway through production of the new season.

Longmire season 4 is scheduled for release in the fall though the streaming site has not yet announced a specific release date.
