Hamill, who starred in the first trilogy as Luke Skywalker, has explained that he has been intrigued by the sequel's development without the influence of George Lucas, reported Digital Spy.
"The most interesting aspect from my point of view is that (Star Wars) is now in the hands of the generation who were fans. It's the next generation of filmmakers who were sort of weened on these pictures," Hamill said.
The actor went on to joke about the increased security on the 'Star Wars: The Force Awakens' set.
"Now, I said to them, 'Do I really have to wear this robe and this hood that covers my entire head to go from the trailer to the sound stage?' They said, 'Yeah, there's drones.' Seriously! There's drones flying over the studio trying to get pictures of whatever they can get pictures of," he added.
'Star Wars: The Force Awakens' is due for release on December 18, 2015.
