Shark! Celebrity Infested Waters
9pm, ITV1
At the risk of sounding cold-blooded, the fact that no celebrity gets gobbled up by a shark ruins any real jeopardy in this new reality series. Lenny Henry, Lucy Punch and Ross Noble are some of the stars swimming with their new fish friends – the aim being to prove that sharks are misunderstood. But they’re a good bunch and it’s worth rooting for Helen George – who is too scared to even go in the sea with her kids – as she dives straight in with bull sharks. Hollie Richardson

Dog (Channing Tatum, 2022), 7pm, Film4
Channing Tatum could have made any film he wanted for his directorial debut, and it’s telling that he ended up making Dog. On the surface, Dog is a Turner & Hooch rip-off about an army ranger who has to escort his dead friend’s dog across the country to be put down. However, the number of layers Tatum manages to fold in are incredible. There’s comedy, and a surprisingly clear-eyed take on mental health in the military. And you’ll probably cry at the end. So much better than it needed to be. Stuart Heritage
