ELGIN — A world of pure imagination awaits theatergoers at the Elgin Opera House this month.

Based on the works of Roald Dahl, “Charlie and the Chocolate Factory” is a revised Broadway musical that adds to the content from the 1971 movie, “Willy Wonka and the Chocolate Factory.”

“It has a lot of great music in it that we’re familiar with and a lot of new tunes as well,” director Terry Hale said. “I think there are a little more depth to the characters, and it’s a little more spectacular. The old Wonka script is classic, but this one, I think they added a little more punch.”

“Charlie and the Chocolate Factory” runs Sept. 21 to Oct. 12 at the Elgin Opera House, 104 N. Eight St. Tickets are available at www.elginoperahouse.com.

The musical follows young Charlie Bucket as he finds one of five golden tickets that grant behind-the-scenes access to a chocolate factory run by the mysterious Willy Wonka. In his first major role on the Elgin Opera House stage, Emrik Davis plays Charlie.

“It’s pretty great,” Davis said. “I’ve read almost all the Roald Dahl books, and ‘Charlie and the Chocolate Factory’ is one of my favorites. I really enjoy it.”

Davis said there are a lot of things to focus on at once, but he’s enjoying the experience of acting. His favorite scene is with the great glass elevator.

Playing Willy Wonka, Liam Bloodgood’s favorite scene is the start of Act 2.

“The scene is called ‘Strike It, Reverse It,’ and it just shows how crazy the inside of Wonka’s brain is,” he said.

Bloodgood has spent time researching and practicing bringing the iconic and eccentric Willy Wonka to life, from physical mannerisms to voice inflections.

“I’ve enjoyed the process of becoming Willy Wonka. I feel like it’s a great honor,” Bloodgood said. “I’m going to try and blend each of the different Wonkas all together to try and create a fun amalgamation from all of them.”

Bloodgood also has more than 200 lines to memorize, some of which go by quickly.

“The dialogue and the lyrics all go by pretty fast, but if you don’t pay attention, you’ll miss a joke. There are so many jokes packed into this show,” he said.

Alongside Charlie Bucket and Willy Wonka, “Charlie and the Chocolate Factory” will feature Oompa Loompas and a quartet of parents and their ticket-finding children. In the Opera House production, there are two casts of children for Veruca, Violet, Augustus and Mike.

“We have Cast 1 and Cast 2, and what’s really incredible during the rehearsal process is I’ll work with Cast 1, and I’ll think, ‘these kids are the best,’ and then I’ll work with Cast 2 and I’ll think, ‘Oh, my gosh, these kids are the best.’ They really both have something special to their performance, and you won’t be disappointed with either cast,” Hale said.

For Hale, bringing this performance to the stage culminates more than a decade of waiting.

“I saw this show on Broadway when it first came out — as a matter of fact, I saw the first performance on Broadway, which was fun,” Hale said. “I love the new script that they have. When I was watching the show, I started to imagine what I could do in my space, on the Opera House stage. I’ve been wanting to do ‘Charlie and the Chocolate Factory’ for years. Literally the moment that MTI released the rights, I booked it.”

All performances are at the Elgin Opera House, 104 N. Eighth St. in Elgin. Tickets are available at elginoperahouse.com.
