Rosario Dawson Surprised by Mark Hamill's Return as Luke Skywalker on 'The Mandalorian' Set - Star Wars Celebration

Mark Hamill's surprise appearance as Luke Skywalker in The Mandalorian stands as one of the most thrilling moments in Star Wars lore. Rosario Dawson shared with us at Star Wars Celebration that she was completely in the dark about his cameo until Hamill unexpectedly appeared on the set of The Book of Boba Fett.

It's well-known that Dave Filoni and Jon Favreau cleverly used Jedi Master Plo Koon as a decoy to keep Luke's cameo under wraps. However, during our conversation, they also shared a humorous account of how Dawson experienced one of the biggest surprises of her career due to an accidental oversight in communication.

To maintain the secrecy of Luke's involvement, the scripts featured Plo Koon instead, and Dawson was not spared from this deception. She recounted her confusion upon reading about Plo Koon's arrival in the script for The Book of Boba Fett, a character fans knew had met a tragic end in Revenge of the Sith.

"I was like... I don't know... but people disappear and then they come back, so maybe it's possible?" Dawson remarked. "And then Mark Hamill was on set and surprised me and it was a whole thing. He even said, 'Plo Koon? That wouldn't even make sense!' and I'm like, 'I know it didn't make sense, but I still had to think it made sense because I got the script and everything!'"

Favreau and Filoni expressed their regret over the mix-up, admitting, "That was bad on us!"

"There were two secrets we knew we had to keep on the show," Favreau explained. "One was Grogu's reveal at the end of the first episode, and the other one was Luke Skywalker at the end of season two. We were biting our nails all the way the whole way through, and we somehow miraculously made it cleanly to both of those because everything else leaked. But, unfortunately, we didn't fill in our partner here."

Dawson took it in stride, jokingly saying, "I love it, they know I can't be trusted."
