While the world is still in shock over the death of Robin Williams, those who knew and loved the 63-year-old old actor are taking to social media to pay tribute to him. People like Edgar Wright, Conan O’Brien, John Travolta, Bill Cosby, and Ben Stiller, along with former co-stars, musicians, and many many more have been sharing their thoughts about the Academy Award-winning actor, who made so many people smile with his work on and off screen.

Robin Williams appeared in several projects for the Walt Disney Company, including TV’s Mork & Mindy, 1988’s Good Morning, Vietnam (for which he earned his first Oscar nod), and the 1992 animated feature Aladdin, in which he voiced the Genie. In tribute, the studio released an image of the Genie in the sky created from stars. See the image here below.

The image was created by Eric Goldberg, who was the Supervising Animator for the Genie in Aladdin, and includes a message about Williams by Robert A. Iger, the chairman and CEO of The Walt Disney Company. Here’s the full text (via BuzzFeed):

Along with the aforementioned projects, Williams also starred in Disney’s Flubber, Dead Poets Society, and Jack, and contributed to several of the company’s theme park attractions – “The Timekeeper,” where he voiced the titular character, and “Back to Never Land,” a film attraction at Hollywood Studios.

I am named after a character from a Robin Williams TV show when my parents still lived in Africa. He meant so much, to so many, so far away.

When I was 18 I got a job as an intern at Comic Relief just to be near him. A genius and a truly kind man who made the world a better place.

I cannot believe Robin Williams is gone; he was both a very famous & yet still underrated actor; whether Mork or Garp, a real comedy genius.
