Mark Hamill is set to reprise his role as Luke Skywalker in Star Wars: Episode VII where he teased some information on what fans are about to see.

Episode VII Has Another Filming Location?

On Wednesday, Orlando Sentinel reported that the actor has been getting in touch with his exercises to prepare for his role as Luke once again. He then mentioned some moments on the set that he's witnessed so far.

"I've altered my diet. I've started working out," Hamill said. "There's that. But on the film itself: I toured the departments, I've looked at wardrobe, and I saw the creature shop. I went around and met all the cast people, saw the technicians working on some new things."

The actor also revealed that the reason why everyone involved with the film is keeping it a secret is because they want viewers to be surprised.

"I tell people we're not trying to annoy you or tease you or play some massive game," Hamill said. "Basically what the goal is to keep the surprises for the movie instead of spoiling them on the Internet."

The actor also pointed out what it was like to be back on set after such a long period of time.

"I hasn't seen Tony Daniels or Carrie [Fisher] or Harrison [Ford] or Peter Mayhew in ages...it was wonderful to see them again, because I didn't expect to," he said. "Again, this is all so unexpected. It's like getting out that pair of pants you haven't worn in five years and finding a 20-dollar bill in the pocket. Oh, this is nice."

Star Wars: Episode VII is expected to hit theaters on December 18, 2015.
