During the "Stars of the Saga - Star Wars Celebrity Talk Show," Blake entertained audiences with stories of his experiences portraying some of the more unusual characters in the prequels, while Mayhew reminisced about his role as one of the most beloved characters in the original trilogy.

Blake, most noted for his role as the slimy Neimoidian schemer Rune Haako, has also stepped into the shoes of Mas Amedda -- the booming voice of order in the Galactic Senate -- as well as the shaggy-haired serpentine Jedi MasterOppo Rancisis, Watto's tall-crested betting partner Graxol Kelvyyn, and alien senators Orn Free Taa and Horox Ryyder.

"I seem to always be playing the dodgy characters," Blake laughs.

When Blake first auditioned for The Phantom Menace, he and fellow actor Silas Carson were put to work shooting animatics of the submarine scene playing the parts of Qui-Gon (Blake) and Jar Jar (Carson). Even though Liam Neeson and Ahmed Best played the intrepid heroes in the final film, Blake joined Carson in the Star Wars universe depicting half a dozen notable characters.

To the audience's delight, Blake mentioned that his latest movie project will have him working closely with none other than Star Wars alumnus Warwick Davis (Wicket).

"I'm working on a little movie called Hitchhiker's Guide to the Galaxy," Blake says over the applause. "Have you heard of it?"

Hitchhiker's is being shot in the same place Star Wars made famous, Elstree Studios. "When I work there I get the sense that history is creeping out of its very walls," Blake remarks.

After Blake was asked by a fan to do his impression of Darth Vader by breathing into an empty glass, it was Mayhew's turn to take center stage.

When asked by a fan which scene was the hardest to play, the towering 7' 3" actor explained that acting around bluescreen wasn't the only obstacle on the set. Director George Lucas asked Mayhew to pretend to play against R2-D2 in a friendly game of holographic chess in the Millennium Falcon in A New Hope.

"He said to just pretend as though I was playing chess," Mayhew says. "But of course I'd never played chess in my life, not to mention against droids. So I faked it."

Mayhew also went on to describe what it felt like to meet one of his heroes while he was being fitted for his Wookiee costume last year on the Sydney Episode III set.

"I met Christopher Lee and was completely awestruck," Mayhew recalls. "When I shook his hand he said, 'I think you have more screen-time than I do.'"

To the audience's surprise, right when Mayhew reminded fans that Episode III is scheduled to be released on his birthday of May 19, 2005, his alter ego Chewbacca, accompanied by a few Ewoks, walked on stage with a chocolate birthday cake to celebrate Mayhew's recent 60th birthday.

"Chocolate is a Wookiee favorite," Mayhew smiled.
