Fans of The Flight Attendant and Based on a True Story will love Kaley Cuoco's new show - but the actress admitted she had her reservations about signing on to film Vanished. The MGM+ series, which premiered on Sunday, February 1, introduces Alice (Cuoco), who goes on a romantic getaway with boyfriend Tom (Sam Claflin) - only for him to disappear. The show was primarily filmed in Paris and Marseille, which gave Cuoco pause at the time.
