Will Smith Thanks Jackie Chan for His 'Eternal Impact' on Smith Family in Heartfelt 70th Birthday Message

Smith's youngest child, son Jaden, starred alongside Chan in the 2010 remake of 'The Karate Kid'

Will Smith is sharing his gratitude for Hollywood legend Jackie Chan on the actor's milestone 70th birthday.

The Oscar winner saluted Chan with a touching Instagram post on April 7, in which he thanked the actor for the "eternal impact" he's left on the Smith family. Smith's youngest child, son Jaden, 25, notably starred alongside Chan in the 2010 remake of The Karate Kid.

"Happy 70th (wow) Birthday to My Guy @jackiechan!! In addition to making some of my FAVORITE movies of all time, creating some of the CRAZIEST moments that have ever been captured on film — I thank you most for helpin’ to raise Jaden," Will, 55, captioned a series of photos featuring Jaden with Chan.

"Our time with you in Beijing during the Karate Kid left an eternal impact on our entire family. We wish you the deepest Love & Revelation on your next trip around the sun ☀️," he added.

Will's post was full of heartwarming snapshots of himself, Chan and Jaden — including a few of the trio on the set of the film, and one in particular where Will and Chan held up Jaden while behind the scenes in Beijing.

Chan — who is set to return to the next Karate Kid film alongside Ralph Macchio — spoke to George Lopez in 2010 about how Will "called my office" to present him the pitch for the 2010 blockbuster. Will and Jada Pinkett Smith served as producers for the film, which ended up grossing an estimated $359 million worldwide, per IMDB.

"I said, 'OK! Who's the teacher?' " Chan laughed at the time about Will's phone call. "I thought, 'I'm the karate kid!' "

"I already forget how old I am," he added. "I still think I'm the kid. He said, 'No, you're the teacher. My son's gonna be the Karate Kid.' "

On his 70th birthday, Chan shared a heartfelt post of his own on Instagram, expressing his gratitude for being “able to grow old” despite all the stunts he's taken on over the decades.

In a caption for the post, which included several images of Chan over the years, the actor explained that many of his friends had been reminding him that his 70th birthday was coming up.

"Every time I hear this number, my heart would stop for a second — l’m 70 years old already?” Chan began a lengthy caption. “After recovering from the shock, the second thing that would come to my mind is a saying that my big brother, Sammo Hung once said: ‘Being able to grow old is a fortunate thing.’ Especially for us stunt people, we don’t know how lucky we are to be able to grow old.”

Chan later added that recent photos of him circulating online with "white hair, white beard and [looking] old" are only for a character, and that he's “always been willing to try new things for a movie, no matter if it’s a challenging stunt or a breakthrough appearance for a character."

Addressing the photos he shared on his page, Chan wrote: “Looking at these photos brings back so many fond memories. All I can say is: I love making movies and I love you all. A big thank you to everyone for all your birthday wishes. Hope everyone stays happy and healthy!”
