Intruders BBC2, 9pm
Any new series featuring John Simm is always worth a look, but when you hear he’s appearing in something that has already gone down a storm in the US, it becomes a must-see. The plot focuses on a shadowy organisation dedicated to chasing immortality by inhabiting other people’s bodies. Simm stars as ex-LA cop Jack Whelan, who becomes suspicious of the group’s activities after his wife Amy disappears. Mira Sorvino, James Frain and Tory Kittles also star. ’Intruders is a truly unsettling drama – eerie, intriguing, complex and compelling,’ says Sue Deeks.
