No Return has held viewers gripped with the story of a dream family break turned into a holiday from hell.
The tense series screened on ITV and ITV Hub has a stellar cast with national treasure Sheridan Smith playing distraught mum Kathy Powell whose son Noah is accused of sexual assault.
And the teenage actor at the centre of the action, Louis Ashbourne Serkis, comes from acting royalty.

His parents are Marvel and Lord of the Rings star Andy Serkis and his mother is Lorraine Ashbourne, star of the hit Netflix dramas Bridgerton and The Crown.
Louis, 17, has previously appeared in the movies The Kid Who Would be King and Alice Through the Looking Glass and the TV shows Endeavour and the Queen's Gambit.
He also starred opposite and was directed by his dad in the film Mowgli: Legend of the Jungle in 2018 as Bhoot, an albino Indian wolf cub in Akela's pack and Mowgli's friend.
No Return viewers clocked the likeness between Louis and his famous father, who is known for his motion capture roles in some of the biggest films of all time including his role as the monstrous Gollum in Lord of the Rings and supreme leader Snoke in the Star Wars franchise.

@Conderoni marvelled jokingly: "Absolutely mad that Andy Serkis is playing his own son through motion capture rather than just letting him give it a go #NoReturn."
