Roman Polanski and Danny De Vito are among the big attractions at the world's first and foremost children's cinema festival, which is currently taking place in this small southern Italian town.
X-files actress Gillian Anderson is also coming to the 37th Giffoni Film Festival, which kicks off on Tuesday with the Italian Premiere of Harry Potter and the Order of the Phoenix.
But the real stars are the kids who will bring the 11-day show to life.
These include 2,000 child jury members from 30 different countries, including Israel, the Palestinian Territories, Mexico, the USA and Belarus, who will pick the prize winners.
"By involving thousands of youngsters we are promoting passion for cinema, commitment and values at this edition of the Giffoni Film Festival, just like we do every year," said Claudio Gubitosi, the festival's founder and director.
The youngsters will be able to enjoy Italian previews of The Simpsons Movie, Shrek the Third and Ratatouille, the story of a rat who risks his life in a French bistro to satisfy his love of fine cuisine.
Persepolis, the French animation movie about an outspoken Iranian girl which won the jury prize at Cannes this year, is also among the 54 films being screened in out-of-competition sections.
C/O Footpath, by 11-year-old Indian boy Kishan Shrikant - the world's youngest feature film director, according to organizers - is one of 64 movies taking part in the five competitive sections.
Shrikant started out in the film industry as an actor at the age of four. He has appeared in an Indian soap opera and over 24 films.
His directorial debut is about street children who have no other address than the footpaths of India's big cities.
Gubitosi first organized the Giffoni Film Festival, which focuses on films for, and sometimes by, children and teenagers, in 1971.
It is now considered the most important event of its kind.
During its long history the festival has attracted a number of film greats to the sparsely populated town hidden in the hills of Salerno province.
Past guests of honour include actors Robert Di Niro, Anthony Quinn, Alberto Sordi and directors Franco Zeffirelli and Bernardo Bertolucci.
Former Soviet President Mikhail Gorbachev came in 1997.
