Mosaic (Saturday, Sky Atlantic, 10pm)

Sharon Stone plays a successful children's author, Olivia Lake, who lives in a super-affluent neighbourhood among the ski resorts and mineral mines of Utah, where the ultra-rich residents seem to set their own rules, and are ruthlessly protective of the moneyed status quo. When Olivia disappears in suspicious circumstances, all the nasty little secrets and lies soon come to the surface. Look out for other blasts from the past in the cast, including Paul Reubens and Beau Bridges.

Troy: Fall of a City (Saturday, BBC One, 9.10pm)

David Threlfall, Frances O'Connor and Louis Hunter are among the cast who work like Trojans to bring this semi-mythical tale to life.
