Comedy icon Dick Van Dyke celebrated his 100th birthday on Saturday, hitting the century mark some six decades after he sang and danced with Julie Andrews in “Mary Poppins” and starred in his self-titled sitcom.

“The funniest thing is, it’s not enough,” Van Dyke said in an interview with ABC News at his Malibu, California home. “A hundred years is not enough. You want to live more, which I plan to.”

Van Dyke became one of the biggest actors of his era with “The Dick Van Dyke Show,” which ran from 1961-66 on CBS; he appeared with Andrews as a chimney sweep with a Cockney accent in the 1964 Disney classic “Mary Poppins” and, in his 70s, played a physician-sleuth on “Diagnosis: Murder.”

Also a Broadway star, Van Dyke won a Tony Award for “Bye Bye Birdie” to go with a Grammy and four Primetime Emmys. In 1963, he starred in the film version of “Bye Bye Birdie.”

Just last year, he became the oldest winner of a Daytime Emmy, for a guest role on the soap “Days of Our Lives.”

In the 1970s, he found sobriety after battling alcoholism, gaining recognition for speaking out at a time when it was uncommon to do so.

Reaching triple digits has given Van Dyke some unique perspectives on aging, particularly how he used to portray 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 shared wisdom about living to 100 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, for keeping him young.

“She gives me energy. She gives me humor, and all kinds of support,” he stated.

Van Dyke was born in West Plains, Missouri, in 1925, and grew up “the class clown” in Danville, Illinois. He discovered his passion for acting at a young age, starting when he was about 4 or 5 years old in a Christmas pageant.

Reflecting on his age, he expressed, “I miss movement,” adding, “I’ve got one game leg from I don’t know what.”

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