Hollywood remembers James Bond star Roger Moore

Hollywood has lost an icon.

Roger Moore, the actor best known for his long run as James Bond, has died at 89, his personal assistant Gareth Owen confirmed to USA TODAY. Moore's children said in a joint-statement that he died Tuesday after a "short but brave battle with cancer."

The news of Moore's death was met with an outpouring of grief from celebrities and fans on social media. Charity organization UNICEF, for which Moore was a Goodwill Ambassador, released a statement saying he will be "deeply missed."

"With the passing of Sir Roger Moore, the world has lost one of its great champions for children – and the entire UNICEF family has lost a great friend," the statement read. "In his most famous roles as an actor, Sir Roger was the epitome of cool sophistication; but in his work as a UNICEF Goodwill Ambassador, he was a passionate – and highly persuasive – advocate for children. He once said that it was up to all of us to give children a more peaceful future. Together with Lady Kristina, he worked very hard to do so."

PETA wrote, "Animals have lost a dear friend with the passing of Sir Roger Moore," recalling his successful campaign to convince British department store Selfridge's to stop carrying foie gras, as well as his call for the Queen's Guard to replace their bearskin caps with faux fur. " He called out animal abuse with wit and charm, and PETA will continue campaigning to help the animals he cared so deeply about," they promised.

Longtime friend Joan Collins remembered him as "the kindest, warmest, wittiest gentleman."

Bryan Cranston shared a photo of himself with Moore, explaining that he met with the late actor six months ago.

Russell Crowe was short in his tribute, noting that he "loved" Moore.

Kris Jenner called him the "ultimate" Bond.

Director Edgar Wright noted that Moore was his first Bond as a kid.

The band Duran Duran — which performed the title song for Moore's final Bond film, A View To Kill — paid tribute.

Mia Farrow said that "few are as kind & giving as was Roger Moore."

Composer Andrew Lloyd Webber tweeted his love.
