Mary Poppins actor Dick Van Dyke has starred in Coldplay’s latest music video as he prepares to celebrate his 99th birthday.

Filmed at his beachfront home in MalibuIn the moving video, the star remembers his life and reflects on aging.

“I’m fully aware that I could leave any day now,” he says, “but I don’t know why it doesn’t affect me. I’m not afraid of it. I feel like I’m going to be okay.

The video is based on the ballad “All My Love” and was co-directed by Mary Wigmore and Academy Award-winning filmmaker Spike Jonze, whose films include “Being John Malkovich,” “Her” and “Adaptation.”

The seven-minute film is a touching and intimate portrait of the popular actor, who has appeared in films such as “Chitty Chitty Bang Bang”, “Bye Bye Birdie” and the TV show “Diagnosis: Murder”.

He gives the filmmakers a tour of his house and shows memorabilia from his films – including a life-size replica of Bert, his chimney sweep character from Mary Poppins.

The star also recreates himself The Twizzle (an incredibly flexible routine from his 1960s TV sitcom “The Dick Van Dyke Show”) while Chris Martin serenades him on the patio of his home; and dances barefoot with his wife Arlene Silver.

The most emotional moment, however, comes when he talks about his four children, Christian, Barry, Stacy and Carrie Beth.

Looking lovingly at a photo of Stacy being read to her a bedtime story, Van Dyke reveals, “I’ve had dreams where I was depressed, lonely, hurting, and she comes to comfort me. She actually comes to comfort me.”

His family – including dozens of grandchildren – arrive later in the video, dancing and singing with the actor, who tells Martin that he is particularly fond of one line from “All My Love”: “Until I die / Let me hold you when you cry.“

The video ends with Martin improvising a song for the star, who watches in amazement as the music comes to life.

“Did we film that?” he asks. “Can you believe this man?”

“All My Love” is the latest single from Coldplay’s tenth studio album “Moon Music,” which debuted at number one in October.

The group took an idiosyncratic approach to promoting the album. Hosting a segment on the shopping channel QVC, and Filming a spontaneous video for the song We Pray in the middle of Dublin’s Grafton Street, just before they played a show at the city’s Croke Park Stadium.

Chris Martin also appeared in an earlier video for All My Love Walking through the streets of Las Vegas in disguiseSinging karaoke and handing out balloons to strangers… a scene that Van Dyke briefly recreates in the latest clip.

In an interview on the US talk show Jimmy Kimmel Live! Martin revealed that he and Van Dyke were neighbors in California and had been friends for years.

“This might actually be the funniest thing I’ve ever done,” he said of the video.

“That makes me so grateful. It’s a big deal for me.”

The video premiered on the band’s YouTube channel. A shorter version will be released on December 13th to mark Van Dyke’s 99th birthday.
