The actor, who played the teen comedy’s titular lead, addressed network The CW’s decision to axe the show on Instagram.
Hale tearfully told fans: “I didn’t just want to post a picture or a caption because nothing would do justice to how I feel about Katy Keene or how I feel about the people involved with it.
“Truly one of the highlights of my life. Just such a joy, from top to bottom.”
Hale, whose shows Life Sentence and Privileged were also cancelled by The CW after one season, added: “It’s happened a few times to me, and each time it’s just heartbreaking… This is a bad one, it’ll take some time to get over but that’s not why I’m making this video.
“Mainly I wanted to make this video so you could hear it straight from me so nothing is misconstrued.
She stated: “Long story short, I am just grateful. I’m grateful for the role of a lifetime, what a blast.”
Thanking her colleagues and the show’s creators Roberto Aguirre-Sacasa and Michael Grassi, she said: “I’m so proud of what we made. I do believe it’s timeless. I think sometimes things just don’t work out and maybe it was just not the right time for it. I don’t know, I’m a little confused.”
Katy Keene is a musical comedy-drama based on the Archie Comics character of the same name.
It chronicles the origins and struggles of four aspiring artists trying to attain successful careers on Broadway, on the runway, and in the recording studio.
