- In general the phoenix – as an existing myth and not attributable to specific elements of the film by Maestro Bertolucci – references a basic theme akin to the karmic themes addressed in the movie "Little Buddha" and that is to say to rise from one's ashes, which in my opinion approximates the topic of Reincarnation

 

- In the 4th film there is the advice to use plants from Tibet to breathe underwater

 

- In Little Buddha at the monastery there is an Oracle who falls into a convulsive trance to divine, while in Harry Potter there is a Seer (Professor Trelawney) who makes predictions in a state of convulsive trance

 

- In the scene where Mara attacks Siddharta under the tree, through an army of warriors, you can find suggestions: the simple fact of turning fire arrows into flowers and petals evokes the magic, also those flaming arrows may recall the magic attack by Voldemort at Hogwarts barrier in the 8th film

 

- Harry Potter is primarily a series of books and we know about the Buddha from his written teachings, as well as seeing a book about his life read by Jesse (a children's book)

 

- Little Buddha in the very intentions of Maestro Bertolucci is a movie for children. In his interview to MoMa he says: “Before even starting to write I went to see him. (the Dalai Lama) And when I asked him that I would like to do a movie explaining Buddhism to the children, because in the West we have such a confused idea about Buddhism, he laughed and said that’s good. And then I said “Can I call it Little Buddha? Because it’s like Buddhism explained to children.” And he said “Yes.” And he said “You know, we all have a little Buddha inside.”
