Directed by Tony Award winner John Rando, the Oct. 27 gala event will feature The Encores! Orchestra led by Encores! music director Rob Berman.

Hilty earned acclaim for headlining the 2012 Encores! production of Gentlemen Prefer Blondes. She was recently the star of the one-night-only Broadway concert of the fictional "Smash" musical Bombshell. Her stage appearances also include Wicked and 9 to 5. On screen, she's appeared in "Sean Saves the World" and the upcoming "Untitled Warren Beatty Project," scheduled for release in 2016.

Additional casting will be announced at a later date.

Annie Get Your Gun has music and lyrics by Berlin and a book by Herbert and Dorothy Fields. The musical is loosely based on the story of sharpshooter Annie Oakley and her tempestuous romance with gunslinger Frank Butler.

The score includes "You Can't Get a Man With a Gun," "There's No Business Like Show Business," "I Got Lost in His Arms" and "Anything You Can Do." The original production starred Ethel Merman as Annie Oakley.

The gala begins with a 5:30 PM cocktail reception, followed by the 6:30 PM performance. A post-show dinner will be held in the Grand Ballroom of The Plaza Hotel. Benefit tickets range $5,000-$25,000. For additional information and show-only tickets (starting at $35), visit NYCityCenter.org.
