Leonardo DiCaprio auditioned for the film and turned down a role.

In a 2014 interview with Variety, Leonardo DiCaprio talked about turning down the role of Max Dennison in  "Hocus Pocus."

According to DiCaprio, he declined the role to hold out for a part in 1993's "What's Eating Gilbert Grape," which he hadn't even auditioned for at the time.

"I don't know where the hell I got the nerve," DiCaprio said. "You live in an environment where you're influenced by people telling you to make a lot of money and strike while the iron's hot. But if there's one thing I'm very proud of, it's being a young man who was sticking to my guns."

Fortunately, he got the role in the other film. 

Two actors helped bring Thackery Binx's character to life.

"NCIS" star Sean Murray played the human version of Binx and actor Jason Marsden provided the voice of Binx in feline form.

The director of "Hocus Pocus" also worked on other popular Disney films.

Kenny Ortega, the director of this beloved Halloween film, was also involved in the creation of Disney's "Newsies," the "High School Musical" films, and "The Cheetah Girls 2."

Each character had distinct broomstick choreography.

According to an archived press release, the film's choreographer, Peggy Holmes, said each of the Sanderson sisters flew their brooms "in character."

"Each actress flew in character," explained Holmes. "Winifred is in charge and much more aggressive than the other two. She's always leading the way and looking for children. Sarah loves to fly. She's always lifting up with her mop and can't wait to get up in the air, whereas Mary is more cautious. Like a good driver, she signals with her hand. Mary is the safe and steady flier."

Multiple cats were used on set to play Binx.

Due to the length of the film and the variety of tricks required by Binx's character, several cats were used on the "Hocus Pocus" set, reported Humane Hollywood.

Vinessa Shaw, who played Allison, said she was close to Omri Katz, who played Max.

Talking to ABC in 2015, Vinessa Shaw said, "Omri's such a cool dude. We were best buds. We were good friends. He didn't make me feel nervous at all. Anything that was tension-building, we'd just laugh."

Real moths fly out of Billy's mouth in the film.

The actor who played Billy in "Hocus Pocus" actually had real moths in his mouth. 

In an interview with Bloody Disgusting, Alterian Inc's makeup FX master Tony Gardner said a make-up artist created a "mouth rig" to make the moths come out. It was a latex pocket attached to dentures that blocked off Jones' throat.

"There was a small hole in the very back of the pocket so that Doug could cough some air through it and force the fuller's earth and the mouths up and out of his mouth. Once the pocket was loaded with the Fuller's earth, an animal wrangler would place several moths in the pocket with tweezers, under the supervision of a representative from the Humane Society," he told the publication. 

The film was almost called "Halloween House."

According to the Post Mortem Podcast with Mick Garris, "Hocus Pocus" was originally bought by Walt Disney Pictures in 1984 under the name "Disney's Halloween House." 

"Hocus Pocus" wasn't released around Halloween.

Originally released in the US in July 1993, the Halloween-centric film wasn't released in the autumn, which may have contributed to its less-than-stellar box-office performance.

The original trailer features deleted scenes.

In the original trailer of the film, two scenes were shown that didn't end up in the final movie. You can still watch the original, grainy trailer on YouTube.

"Hocus Pocus" has a book sequel.

There is a sequel to "Hocus Pocus" in book form.

"Hocus Pocus & the All-New Sequel" was released for the 25th anniversary of the film and was published in 2018.

And a few years ago, in 2017, Disney Channel announced plans to remake the cult classic "Hocus Pocus" as a TV movie. As of 2019, there has still been no update on this remake.
