"I really, really would have loved to have known Heath today, at 40. No limits on what he would have accomplished," Bosworth wrote of Ledger

Kate Bosworth is honoring friend Heath Ledger on what would have been the late actor’s 40th birthday.

The 36-year-old actress shared a black and white photograph of Ledger on her Instagram account Thursday in which she recounted how the two met, including the positive influence he had on her life and the lives of others.

“Doesn’t seem so long ago we were all running around LA, shotgunned into Hollywood + popping off the new millennium’s cork, having a laugh. It was a crazy time,” she wrote in the caption. “I was literally straight out of high school, feeling young & super shy and he was always so sweet within a surreal scene.”

She continued, “I really, really would have loved to have known Heath today, at 40. No limits on what he would have accomplished.”

“Here is what I remember: he was sensitive, gentle, kind, wickedly funny. Extraordinarily special. Time goes by, his image still a teenage heartthrob. And his work. So brilliant + honest & he was just getting started,” she added. “But to remember the Human. I was on the outer orbit. Imagine those close to the sun. Thinking of all the people who knew and loved him on this day. Man, you made one hell of a mark. xo.”

Ledger died at the age of 28 in 2008 from a fatal mix of prescription drugs in his system. He was survived by his daughter, Matilda, with actress Michelle Williams.

Since his death, The Dark Knight actor has been remembered by his friends, costars and family members, all of whom celebrated his talent and charm.

Maggie Gyllenhaal, who worked with him on the 2008 Christopher Nolan film, honored him during a 2018 interview on Watch What Happens Live with Andy Cohen.

“I remember coming to work and seeing him — that scene where the Joker throws me off a roof — and seeing him come in and start to do what he was doing, which was the first time I saw it,” she said. “I still think about this sometimes — it’s so hard to be good in a huge movie like that, that’s not about the acting, really. It’s so much easier to be good in a little tiny movie where it’s all about you.”

She continued, “To be amazing like Heath was in a movie that’s got explosions and huge stunt scenes and big sets is a whole other thing. I don’t know if anyone’s ever, ever done that as well as he did in The Dark Knight.”

After his death, Ledger went on to posthumously win a Best Supporting Actor Oscar for his performance in 2009 after his death.
