Vigil
9pm, BBC One
Lovesick creator Tom Edge pens this ingeniously claustrophobic maritime drama, starring Suranne Jones. When a crew member is found dead on the Trident nuclear submarine HMS Vigil, Detective Amy Silva (Jones) must go aboard to investigate, as the nuclear deterrent cannot be stopped for fear of compromising its secrecy. While the crew write off the death as an accidental overdose, Silva’s questioning raises suspicions of foul play and causes them to close ranks around a secret. Continues tomorrow night at 9pm.

When Ruby Wax Met…
9pm, BBC Two
Ruby Wax is scarcely less engaging in her new life as a cognitive therapist as she was as an insistent and disarmingly blunt interrogator of celebrities. This series continues to recall the sheer intensity of some of those encounters – tonight’s highlight is an astonishingly frank 1996 interview with Pamela Anderson. Phil Harrison

Beauty and the Beast, 3.35pm, BBC One
Disney’s classic animated musical fairytale comes to deliciously ornate, live-action life, with Emma Watson playing the incarcerated beauty Belle. There is a bit of a can-do, mickey-taking feminist edge about her as she confronts the grumpy beast (Downton’s Dan Stevens, behind the furry face). Paul Howlett
