What to watch this weekend.
Celebrity Catchphrase (New series)
Saturday, 6pm, ITV
Stephen Mulhern hosts a celebrity special of the classic game show, with Larry Lamb, Sam Quek and Scarlett Moffatt all trying to guess the familiar phrases in the animated clues. If they can say what they see, they could get the chance to win a £50,000 jackpot for their chosen charity.

Tipping Point: Lucky Stars (New series)
Sunday, 7pm, ITV
Ben Shephard hosts as comedian Paul Merton, actress Sally Lindsay and Made in Chelsea's Jamie Laing take part in the celebrity version of the game show, in which they must answer questions to win turns on an arcade-style machine. Dropping tokens down a choice of four chutes, they hope to knock piles of them off a moving shelf - and the more they collect, the better their chances of collecting the £20,000 prize for their selected charity.
Extinction: The Facts (New)
Sunday, 8pm, BBC One
With a million species at threat, David Attenborough explores the science of extinction and how this has consequences for everyone. The programme examines why biodiversity loss is happening and what it means - not just for the natural world, but for all mankind. The loss of biodiversity threatens food and water security, undermines humans' ability to control the climate, and places humans at greater risk of pandemics. Leading experts including Sir Robert Watson and plant scientist Prof Kathy Willis explain how all groups in the natural world are in decline, and that extinction is now happening up to 100 times faster than the natural evolutionary rate.
The Singapore Grip (New series)
Sunday, 9pm, ITV
For rubber baron Walter Blackett and his family, life in 1941 Singapore is full of wealth and privilege, where the horrors of war-torn Europe are a distant whisper. But when their power and stability are rocked by new arrivals and the looming threat of a Japanese invasion, Walter has a cunning plan. Adaptation of the novel by Booker Prize-winner JG Farrell, starring Luke Treadaway, David Morrissey, Charles Dance, Jane Horrocks and Colm Meaney.
