They say that the bad guys are always the most fun to play and Hayden Christensen relished the moment when, as Anakin Skywalker, he finally got to embrace the Dark Side and be reborn as uber villain Darth Vader.
"It was kind of a thrilling moment lying there on the operating table and seeing that mask come into frame."
The reason he adopts the head to toe body armour is not just for boo-hiss effect, it is because, his human form had been burnt to a crisp by volcanic lava and the shell casing protects what is left of his body.
Once he was iconically suited and booted the 24-year-old Canadian stepped gingerly out onto the set to find the entire crew had gathered to bear witness.
"It was the last day of filming, everyone from the production offices and working on the film came out.
"Putting the whole regalia on and experiencing the sensation of being Vader was great but watching everyone take him in for the first time was really cool.
"People I had befriended, spent time with, they knew I was in the costume but there was excitement and a certain awe. There was fear and respect that needed to be paid, so as I walked past their eyes would light up but then they'd lower their heads and take a step back. It was very empowering."
He was acutely aware that he had to deliver the actorly goods in this one, to make the transition from the tormented teen of the previous film, Attack of the Clones, to become the embodiment of evil in this.
"This was the time I had been looking forward too. There is just more fun to be had, more emotions to explore.
"It's a daunting task taking on a role that has this much attention and as much as possible you try to disregard all of it. Thankfully George had conceived such a well arced character that we just followed the script and his lead."
However, he was more than a little distressed by a line-crossing scene that involved Anakin killing children.
"It took me by surprise when I read it in the script for the first time," he admits.
"But it was a necessary evil, all the Jedi had to go, even the children. This is a dark film and Anakin does some pretty dark things on that downward spiral."
Powerful past performance in films such as Shattered Glass have proved that Hayden has the ability to rise above the role and have a healthy career, post Star Wars - "But it's nice to have the Darth Vader card in my back pocket."
