Legendary entertainer Dick Van Dyke marked a monumental milestone by celebrating his 100th birthday on Saturday. This remarkable occasion comes more than 60 years after he charmed audiences worldwide with his performance alongside Julie Andrews in “Mary Poppins” and captivated viewers in his groundbreaking sitcom.

Speaking to ABC News from his Malibu, California home, Van Dyke reflected humorously on his longevity, stating, “The funniest thing is, it’s not enough. A hundred years is not enough. You want to live more, which I plan to.”

Van Dyke rose to prominence as one of the most beloved actors of his time, thanks to “The Dick Van Dyke Show,” which aired on CBS from 1961 to 1966. His portrayal of a chimney sweep with a charming Cockney accent in Disney’s 1964 classic, “Mary Poppins,” alongside Andrews, remains iconic. Even in his 70s, he continued to captivate audiences as a crime-solving doctor in “Diagnosis: Murder.”

His talents also shone on Broadway, where he earned a Tony Award for “Bye Bye Birdie,” complementing his Grammy and four Primetime Emmys. In 1963, he took his role from stage to screen with the film adaptation of “Bye Bye Birdie.”

Just last year, Van Dyke set a record as the oldest recipient of a Daytime Emmy, awarded for his guest appearance on the soap opera “Days of Our Lives.”

In the 1970s, he found sobriety after battling alcoholism, and spoke out about it at a time when that was uncommon to do.

Now that he has hit triple digits, Van Dyke said he’s gotten some perspective on how he used to play older characters.

“You know, I played old men a lot, and I always played them as angry and cantankerous,” he told ABC News. “It’s not really that way. I don’t know any other 100-year-olds, but I can speak for myself.”

He recently imparted wisdom about reaching the century mark in his book, “100 Rules for Living to 100: An Optimist’s Guide to a Happy Life.” He credited his wife, 54-year-old makeup artist and producer Arlene Silver, with keeping him young.

“She gives me energy. She gives me humor, and all kinds of support,” he told ABC News.

Van Dyke was born in West Plains, Missouri, in 1925, and grew up “the class clown” in Danville, Illinois, while admiring and imitating the silent film comedians.

He told ABC News he started acting when he was about 4 or 5 years old in a Christmas pageant. He said he was the baby Jesus.

“I made some kind of crack, I don’t know what I said, but it broke the congregation up,” he said. “And I liked the sound of that laughter.”

And what’s hard about being 100?

“I miss movement,” he told ABC News. “I’ve got one game leg from I don’t know what.”

“I still try to dance,” he said with a laugh.
