It’s a great success that Waititi achieves with Jojo. He manages to make a funny, tragic, serious film about the dangers of fanaticism. Johaness (aka Jojo) is 10, lives in Berlin towards the end of the second world war. He is in the Hitler youth and he is thoroughly brainwashed. Adolf Hitler is his imaginary friend! This is initially uncomfortable, yet it is from the perspective of a 10 year old, it is funny but also it tackles the serious topics head on. The tone strikes the right balance and that makes the movie work. Jojo’s world comes crashing when he discovers his mom (played so well by Scarlett Johansson) is hiding a Jewish girl in their home. The performances by the young actors are key here and they do a great job. Roman Griffin Davies as Jojo is excellent as is Thomasin McKenzie who plays Elsa and I really loved Jojoj’s friend, Yorki, played by Archie Yates.
