At age 78, Michael Caine isn't sitting it out.
He's in the jungle with The Rock in the hit film "Journey 2: The Mysterious Island."
"I'm quite fit. I'm touching wood here. For a 78-year-old, I get around," says the friendly screen legend.
"I live on the side of a hill and every time I go for a walk down to my garden, it's definitely a walk back up," jokes the London native of how he stays in such great shape.
He's also a man with unique style….including donning some khakis, a wide-brimmed hat and racing off into the trees.
In his new film, he plays a gung ho grandfather who sends a letter to his teen grandson (Josh Hutherson) insisting that he come to the middle of the Pacific ocean to a mystery island where elephants are the size of poodles and bees are like 747s.
"I love that age doesn't matter," Caine says. "I'm leading the bloody adventure. I'm not following and gasping. I'm the one who races ahead through the jungle screaming, 'Life is an adventure!'"
DOING MOVIE STUNTS AT AGE 78
Caine says that he didn't shy away from certain film stunts.
"First of all, they took good care of me on this set," he says.
"It's a funny thing with stunts. I'm the world's worst horseman. But in one movie I led a charge of horses," he says with a laugh.
"If I had fallen off, I would have been trampled to death. It's funny because actors are so full of themselves. They think they can do any bloody thing."
JUST CALL HIM GRAMPS
Caine says he wanted to do "Journey 2" for his grandchildren who light up his life. His beautiful wife Shakira and Caine love every moment of having little ones around the house.
"What happened to me very late in life is I got three lovely grandchildren. One is three and a set of twins who are two.
"I don't make any films the children can go see until this 'Journey 2,'" he says. "I did the same thing for their mother. When she was six or seven, I made 'Muppets Christmas Carol' for her.
"Now, my grandchildren will be able to say, 'I have a grandfather and he rides around on the back of a giant bumblebee with The Rock. What does your grandfather do?'" he says with a laugh.
In fact, his house in London sounds louder than normal this morning because of the kids.
"I really do have a new lease on life because my daughter's home is under renovations, so I have a three year old and twin two years old living with me and I love it. I love having everything messed up," says Caine.
MICHAEL CAINE: "I WILL NOT RETIRE."
Above all, Caine loves his family and his work. This summer he will star in the last "Batman" film called "The Dark Knight Rises."
"I am sad. But I know this Batman will be the best one and I'm touching wood again here. I love the story. Much more I can't say. Director Christopher Nolan will call me up and say, 'Michael, you did an interview and said you were in 'Batman.' I'll say, 'They know I'm in Batman. People saw me in the streets filming it!' It's all so secretive," he says.
Caine often marvels at his life. Born Maurice Joseph Micklewhite in 1933, he has been acting for over five decades. The son of an English fish market porter never expected to become a movie star.
"I'm lucky that I started out as an amateur actor. Amateur means you do something because you love it. I've been doing something and getting well paid for it for decades and it's something I used to do for pleasure.
"Wait, I'm making myself sound like a hooker," he says with a laugh.
"Honestly, I thank God every single day for my life. I can't believe when people ask me, 'Do you believe in God?' My answer always is: 'If you had my life you'd believe in God, too.'"
