-Disappointed that Admiral Ackbar's scenes in TFA were cut and that his deaeth in TLJ was off-screen. "So in The Last Jedi, I was quite looking forward to maybe them giving him something more juicy. We were only given the script on the day when we were shooting that piece of script, so each day I would come to work going, ‘Is today the day when Ackbar gets something a bit more involving?’ And I looked at my script and I went, ‘Oh, Ackbar's going out of the window. Well, that's that then!’ I wasn’t quite dead yet."
And then after he finished filming, he had an emotional moment. "We finished all of our bits and they asked me to come down to camera. And I thought, ‘Oh well, maybe they’re going to say thank you for being one of the heritage characters and giving 30 years and all that.’ But what they did was, they gave me a Millennium Falcon sign that had the day and the date on it, the scene number, and they said, ‘Can you look at camera and say 'It's a wrap?' Because that would be really funny.'...I was actually in tears in the suit because I thought - after everything, after hoping there’d be something, after knowing there wasn't going to be anything else, Ackbar's final moment before he went in to the box was a big joke about ‘It's a wrap.’ They just thought ‘Wouldn’t it be funny?’ And that was the sum total of my life as Ackbar."
-During the scene where Han and Leia reunite, various puppeteers taunted them with mocking lines. Ford asked for another take because he didn't want to do ADR if other characters were laughing over his lines so on the second take they just mime the words. When Rose was asked about the second take by the director, he aired his thoughts not knowing the speakers were on and broadcasting, "Eh, this Harrison guy... is he gonna talk over our laugh? 'cause it's really putting me off." An assistant director told him he was fired, but it was a front since they still needed him to operate his character (Salacious Crumb) for another take. He was allowed to stay and just had to tell people he was the new guy if asked.
-Rose also talked about how Ackbar's reaction in Return of the Jedi was due to his mindset about Vietnam and war in general: "We'd done the deed, we'd won the battle against the Death Star and Richard Marquand came round and said 'I want you all to stand up and dance around and celebrate,' cause we won the battle. I was at the age where I came within about 200 people of being drafted to Vietnam — I had very strong views about war at the time. Although I think it's something to be proud of, I don't think it's something to celebrate, there's a big difference! So when they turned the camera on I thought: Our people have died, their people have died and the weight of it just sunk me down into the chair. And [Richard] got really angry and said 'right, we're going to do this again and this time you're going to get up and dance around'. I said 'If you want Ackbar to dance around then put somebody else in the suit, you got my performance'. And they left it in!"
