Traditionally, war films, musicals, and historical dramas have been the most popular genres, but franchise films have been among the best performers of the 21st century. There is strong interest in the superhero genre, with nine films in the Marvel Cinematic Universe featuring among the nominal top-earners. The most successful superhero film, "", is also the second highest-grossing film on the nominal earnings chart, and there are four films in total based on the "Avengers" comic books charting in the top twenty. Other Marvel Comics adaptations have also had success with the "Spider-Man" and "X-Men" properties, while films based on "Batman" and "Superman" from DC Comics have generally performed well. "Star Wars" is also represented in the nominal earnings chart with five films, while the "Harry Potter", "Jurassic Park" and "Pirates of the Caribbean" franchises feature prominently. Although the nominal earnings chart is dominated by films adapted from pre-existing properties and sequels, it is headed by "Avatar", which is an original work. Animated family films have performed consistently well, with Disney films enjoying lucrative re-releases prior to the home-video era. Disney also enjoyed later success with films such as "Frozen I" and "II", "Zootopia", and "The Lion King" (with its computer-animated remake as the highest-grossing animated film), as well as its Pixar brand, of which "Incredibles 2", "Toy Story 3" and "4", and "Finding Dory" have been the best performers. Beyond Disney and Pixar animation, the "Despicable Me", "Shrek", and "Ice Age" series have met with the most success.
