Watch Chewbacca talk to Han in The Empire Strikes Back using a thick, British accent

In the almost 40 years since Star Wars has been a part of popular culture, there have been hundreds of behind-the-scenes and never-before-seen moments released. They’ve been included as extras on DVD sets, exclusives on 3D Blu-rays, and in the age of social media, the actors and professionals involved in the films have begun tweeting out cool clips.

Peter Mayhew, the actor who put on Chewbacca’s costume and gave fans their most lovable Wookie, tweeted out a new 40-second video showcasing a scene between him and Harrison Ford (Han Solo) on the set of The Empire Strikes Back. As many know, in the films Chewie growls and Han, fluent in the Wookie language, seems to understand him no problem.

Based on footage in this new video, however, it appears that Mayhew spoke regular, old English while wearing the suit to talk to Ford, with the audio swapped out in the editing bay. It’s a little alarming how jarring it is to hear a British accent come out of Chewbacca’s mouth, but the scene does provide a little more insight into the conversations Han and Chewie were having.

The next Star Wars installment, Rogue One: A Star Wars Story, marks the first stand-alone anthology film in the main series. The film follows reluctant hero Jyn Erso (Felicity Jones) and her fellow Rebel fighters as they try to steal the plans to the Death Star from the Empire.

Rogue One hits theaters Dec. 16.
