* Adaptations vary: Some are strict adaptations, while others take more liberties, making it subjective to determine if they qualify.
* Different versions exist: Multiple film versions of the same story exist, like *A Tale of Two Cities* or *Oliver Twist*.
* Unofficial adaptations: Films might be inspired by Dickens' themes or characters without directly adapting a specific work.
However, we can say that dozens of films have been made based on Dickens' novels, with some of the most popular being:
* A Christmas Carol (multiple versions)
* Oliver Twist (multiple versions)
* Great Expectations (multiple versions)
* A Tale of Two Cities (multiple versions)
* David Copperfield (multiple versions)
* The Pickwick Papers
* Bleak House
* Nicholas Nickleby
* Hard Times
* Little Dorrit
Beyond these, many other films have been based on his stories, often with lesser-known titles but contributing to the enduring legacy of Dickens on film.
