It's a pretty chill Sunday on the box, so relax with some sun-soaked adventures on Sky, or maybe Matt Lucas and a gang of celebs, or you could revisit The Riordans, or maybe unwind with a great movie or two . . .

Pick of the Day

Hawaii Five-0, 9.00pm, Sky One & NOW TV

Can’t believe this reboot of the Jack Lord show from half a century ago has lasted ten seasons (great theme tune excepted), but that’s the value of a series that’s an uncomplicated mix of a buddy cop show and Baywatch.

At times like this, especially on the eve of the first phase in the unlocking of restrictions in Ireland, it’s hard not to knock something that puts smiles on millions of faces around this Earth of ours.

Now the legendary martial arts star Chuck Norris guest stars in Hawaii Five-0’s penultimate episode.

Naturally nothing else really matters about this episode, but on the off-chance that you’re interested, Steve McGarrett receives a posthumous letter from his mother that contains a cypher, and Danny is attacked by someone willing to kill to steal it.

Don't Miss

Primates, 8.15pm, BBC One

If there's one thing that Sundays are made for, it's quality nature TV shows on the BBC. Here's yet another in a very long line.

Magnum PI, 8.00pm, Sky One & NOW TV

Another rebooted show that’s both inexplicably popular and around for an entire decade. Reboots are made for walking, eh?

This week, Magnum and Higgins are each hired by a different spouse who are in the middle of a contentious divorce to dig up dirt on the other, and Thomas and Higgins soon find themselves competing over resources.

The Celebrity Chase, 8.00pm, Virgin Media One

Last up, the series looks at how variations on the theme of family are depicted in Australian movie-making.

While staying at a hotel in the Caribbean, Miss Marple investigates the death of a fellow guest, refusing to believe he died of a heart attack.

Cats: The Musical, 8.00pm, Sky Arts

Not to everyone’s taste - I’m certainly not a fan - but the Andrew Lloyd Webber devotees out there will lap up this spectacular stage show.

Prime Time Movie Picks
