Don’t make fun of Harrison Ford on the set of one of his movies or you may find yourself without a job.

That’s the takeaway from YouTuber Jamie Stangroom’s interview with “Star Wars” puppeteer Tim Rose, who says that the Han Solo actor wanted to have him fired for mocking him while shooting a scene for “The Return of the Jedi”.

Rose, who famously portrayed Admiral Ackbar (“It’s a trap”), explained that while filming the iconic scene when Ford’s character is unfrozen after being encased in carbonite, Princess Leia (Carrie Fisher) gives Han a kiss, prompting all the puppeteers playing alien characters in Jabba the Hut’s throne room to chant, “We saw you kissing!”

“Harrison went over to the director and said, ‘Are these puppet characters going to laugh over my line? Because I don’t want to have to come back and do ADR [Automated Dialogue Replacement],'” Rose said.

Following Ford’s directives, added Rose, director Richard Marquand filmed another take of the scene, but told the puppeteers to “do it in mime, don’t make any noise.”

Just before filming a third take, Rose says Marquand sat down beside the puppet character he was operating (Jabba’s pet, Salacious Crumb) and asked Rose what he thought of the previous take.

Not realizing his mic was live and was being played over the speakers, Rose joked, “Eh, this Harrison guy… is he gonna talk over our laugh? ‘Cause it’s really putting me off.”

The film’s crew “found it funny. But Harrison didn’t,” Rose said, telling Stangroom that Ford stormed off the set and refused to return until whoever made the joke had been fired.

According to Rose, a young AD approached him and told him he was sacked, and that there was no point apologizing because the ticked-off actor was “really serious.”

There was one catch, however: because Rose was always costumed as a character while on the set, Ford didn’t actually know what he looked like. As a result, the puppeteer was allowed to keep his job, under the condition that if anyone asked who he was he would say he was “the new guy.”

Decades later, Rose once again worked with Ford on “The Force Awakens” when they each reprised their respective roles, and Rose has nothing negative to say about the actor.

“I’m at great pains to say Harrison Ford is a great guy,” he added. “I just happened to misread the sense of humour and do the wrong thing at the wrong time.”
