Scot Weinger, who played Aladdin in the animated film, said Wednesday that working with his hero was surreal and magical, adding the world has "lost a bright light."
Weinger described himself as a lifelong Willams fan who had a "Mork" doll as a kid and a poster of Dead Poets Society on his wall as an emerging actor. Working with his hero was surreal and magical, he said.
Linda Larkin, who voiced Princess Jasmine in the movie, called Williams a "wild, soulful, boundless spirit," characterizing his Genie character from the movie as "the best gift ever."
Their reaction came a day after the cast of Broadway's hit show Aladdin created their own tribute. James Monroe Iglehart, who won a Tony Award as the Genie, led the crowd at the New Amsterdam Theatre on Tuesday in a rousing version of "Friend Like Me" after the curtain went down. The show's Playbills had been stuffed with the song's lyrics and everyone was encouraged to sing along.
The Broadway community honored Williams by dimming marquee lights for one minute Wednesday at 7:45 p.m. Eastern.
Williams, who died of an apparent suicide in his San Francisco Bay Area home this week, had been on Broadway several times, most recently as a restless tiger ghost in 2011 in Bengal Tiger at the Baghdad Zoo.

The Williams family is asking well-wishers to send contributions to charities close to the actor's heart in lieu of flowers. Suggested organizations include St. Jude Children's Research Hospital, Challenged Athletes, USO, the Muhammad Ali Parkinson Center, the Christopher and Dana Reeve Foundation and Glide Memorial Church in San Francisco.
