South Africa With Gregg Wallace
7.30pm, ITV
Gregg Wallace has escaped the MasterChef kitchen for a jaunt around South Africa in this new six-part food-themed travelogue. Wallace brings his brash narration to the stunning safari landscapes of the Amakhala game reserve in this opening instalment of his 3,000-mile journey. Here, Wallace stares agog at warthogs and giraffes before snacking on some beef biltong and sampling the open-fire stew potjiekos. He then heads out with Dr Will Fowlds to track a leopard.

Bill Murray playing a cantankerous drunk, but secretly harbouring a big, soft heart? What a surprise. Comfortably familiar though the setup is, Murray and Jaeden Lieberher, playing the 12-year-old he grudgingly agrees to babysit, create a plausible and charming bond. Paul Howlett
