Animated films often are labeled as simple stories for kids with fluffy and colorful characters, but this is not always the case. Although many are created exclusively for youngsters, there are also many amazing animated films aimed purely at adults. There are then many great in-between films which have humor for both groups, such as Shrek, but today we will be focusing on animated films which have mature themes and subject matter which would be deemed not appropriate for children. Move aside, Woody, Elsa and Nemo, these are animated films for adults only.
10. A Scanner Darkly
There are few directors as experimental as Richard Linklater, and a great example of this is his fantastic 2006 animated science fiction thriller A Scanner Darkly. This was created using the interpolated rotoscope technique, where the film was shot digitally and then traced over frame by frame, which gives it a very distinctive look. The film, based on the novel of the same name by Philip K. Dick, tells the story of a near-future dystopia with increased surveillance under intrusive technology in the midst of a drug epidemic. An undercover detective, Bob Arctor (Keanu Reeves), is assigned to immerse himself in the drug’s underworld, but he soon struggles to maintain a grip on his own identity and is forced into psychological testing. It is a fantastic, and very relevant, story which deals with mature themes in a stylish and dramatic presentation.
