This year's BBC Children In Need show is taking place on Friday, with highlights including Timothee Chalamet pranking Rylan Clark, and a "challenge squad" of young people completing feats in the name of charity.
Oscar-nominated actor Chalamet and co-stars Zendaya, Jason Momoa and Anya Taylor-Joy will be seen making Rylan sweat during an interview for their new film Dune: Part Three, with the help of three children, hidden behind the scenes.
The show will also feature Radio 2 presenter Owain Wyn Evans, on a 400-mile cycle challenge through Scotland, Northern Ireland, England and Wales.
Last year's appeal raised more than £45m to help children and young people across the UK, and this year's TV event will be broadcast from 19:00 GMT.

The three-hour show will be hosted live from Salford by Alex Jones, Mel Giedroyc, Rylan, Sara Cox and Tyler West.
They will welcome Wyn Evans, who has been the latest Radio 2 DJ to put himself through a gruelling challenge for Children In Need, following in the footsteps of the likes of Sara Cox and Paddy McGuinness.

Wyn Evans is being joined on his final leg in Wales on Friday by 22-year-old Harri, who is living with hidden lasting effects of a brain tumour.
He is part of The One Show's "challenge squad" - four young people who have signed up for a series of personal missions for the charity.

The others are 16-year old Zoe, who has Down's syndrome, who will be seen dancing with the cast of High School Musical; Ana, also 16, who has a rare physical condition and is doing a three-day kayaking challenge; and 22-year-old Serena, who will perform live in memory of her late brother and a childhood friend.
The theme of this year's Children In Need is Challenge Yourself 2026, which has also seen Morning Live presenters Michelle Ackerley and Gethin Jones learn instruments to perform with a band live on the night.
Joe Wicks and Emma Bunton are among the other stars who have been involved, while landmarks including the Blackpool Tower, London Eye and Titanic Belfast will be lit in yellow for the occasion.
Children in Need supports more than 1,600 local charities and projects across the UK.
Children In Need is on BBC One and iPlayer from 19:00-22:00 GMT on Friday.
