Katie Ladner Gives Instagram an All Access Pass Behind the Scenes at Sunset Boulevard

Katie Ladner burst onto the New York scene as Martha Dunnstock in the cult musical adaptation of Heathers. Since then, she's appeared in Disney's Freaky Friday, the off-Broadway musical Gigantic, and Joe Iconis' Be More Chill. She makes her Broadway debut as an absolutely captivating ensemble member in the acclaimed revival of Sunset Boulevard

, starring Glenn Close.

Katie took over the BroadwayBox Instagram on April 29 to bring followers along for a two-show day at the Palace Theatre. Scroll on to relive all the fun!
