If you've never read The Tiger Who Came To Tea, don't worry. We can catch you up on the plot fairly quickly.
The children's classic, written in 1968 by Judith Kerr, tells the story of a young girl named Sophie, who has to stay home with her mum because it's too rainy to go to the park.
Fortunately, the day takes an interesting turn when a hungry tiger turns up at the door and asks if he can join Sophie and her mother for tea.
Spoiler alert: he ends up eating far more than his fair share.
"My mum used to read it to me," explains seven-year-old Clara Ross, who voices Sophie in a new Channel 4 adaptation of the book.
"And then, when I could read, from when I was about four up to now, I would read it to my own tiger - or to my cat Mia who is related."
The rest of the cast is starry, to say the least. David Walliams narrates, while the other characters are voiced by actors including Benedict Cumberbatch, Tamsin Greig and David Oyelowo.
Robbie Williams, meanwhile, has recorded a new original song for the soundtrack, called Hey Tiger. But producer and joint managing director of Lupus Films, Ruth Fielding, said getting an A-list cast on board was the easy part.
"They all loved the book, had read it to their kids, so they said yes straightaway," she explains. "We aimed high and got the best."
Sadly, Kerr died in May this year, which meant she wasn't able to view the finished film. But until her death, she was heavily involved in the production process, personally selecting Lupus Films from a range of companies who wanted to adapt it for TV.
"That burden of responsibility is huge, but also, we weren't worried because we had Judith's help," Fielding says. "She was involved right from the beginning, she was involved in the script, saw the designs, she helped choose the cast, the lyrics to the song.
"So we weren't worried that we'd do a bad job because we had her help, and she was across the whole process. She knew what she wanted, there's no doubt about that!
