Who is in the Into the Deep Blue cast?

Waisglass, who recently made her romance debut with Tubi’s How to Make a Popularity Contest, will star as Fiona.

“Sara IS Fiona,” screenwriter Jennifer E. Archer wrote on Instagram. “She radiates warmth, she’s fiercely talented, and she’s pretty damn hilarious too! She will bring so much heart to this role. I can’t wait to meet Fiona through her eyes. I could not be more in love with her, and y’all are not prepared for the magic that’s about to happen.”

Waisglass’ future scene partner is no stranger to the young adult romance genre. He’s the lead love interest in Prime Video’s German-language series Maxton Hall, which just wrapped filming its third and final season. Waisglass told Swooon that she has yet to watch Hardung’s show, but she’s already started emailing her soon-to-be costar as of December 2025.
