Rebecca Ferguson, star of Apple TV show "Silo," has described it as "one of the happiest jobs I've ever done" working on the show. Ferguson also serves as an executive producer on the series. Despite the underground setting, Ferguson said she felt comfortable working on "Silon" and that it was a love journey for her. She initially rejected the role of Juliette Nichols due to the long time commitment and other small disagreements with the show, but changed her mind when she informed the producers about the changes. The team reportedly liked Ferguson's suggestions and gave her an Executive Producer title due to her involvement.
