Books turned into blockbuster films are more popular with children today than traditional favourites by authors such as Roald Dahl, according to research.
It suggests a disconnect between what pupils are reading in schools - where the exploits of Matilda (inset right), Fantastic Mr Fox and the Wimpy Kid remain common - and the tales they would rather be delving into, such as Harry Potter or the Hunger Games.
The findings also suggest that children are turning their backs on difficult books after they start secondary school.
The UK-based What Kids Are Reading survey showed that the "most read" charts at both primary and secondary level were dominated by the likes of Jeff Kinney and Dahl.
But many spots on the "most popular" lists were commanded by J.K. Rowling, Suzanne Collins, who wrote the Hunger Games trilogy, and Cassandra Clare, who penned The Mortal Instruments series.
These are novels that have tended to appear on the big screen.
The "most read" chart indicates the amount of times a book was read in school, while the "popular" ranking shows books children enjoyed the most.
One author - David Walliams - appears frequently in both lists, particularly for primary schools, with youngsters both reading and enjoying the adventures of the Demon Dentist and Gangsta Granny.
The most read book for primary schools was The Twits, by Roald Dahl.
