Tilda Swinton has appeared in a number of popular films as of late, most notably in Marvel's "Doctor Strange" and the comic book adaptation of "Snowpiercer" (soon to be a TV show!), but she does not think of herself as in the mainstream. In a recent profile in the Scots Magazine, Swinton said, “I’ve actually done very few studio films, and when I do visit Hollywood, I feel like a tourist, and I prefer to keep it that way.” She also had criticism for a certain popular series of films.
Swinton was a student at Lonrdon's West Heath Boarding school. She compared her experience there to hell and called it "a very lonely and isolating environment." That's where her distaste for "Harry Potter" seems to come from. She went on to say, "That’s why I dislike films like 'Harry Potter' which tend to romanticize such places. I think they are a very cruel setting in which to grow up and I don’t feel children benefit from that type of education. Children need their parents and the love parents can provide."
Perhaps it is because she is the mother of two, or maybe she's just seen enough of "Harry Potter" which has made a recent resurgence with a new blockbuster movie in theaters and a popular new book. She described her experiences as a mother as making her "more disciplined and less lazy and irresponsible... I can’t just take off and do anything I want to anymore which is a good and a bad thing, I suppose!”
Maybe she just prefers a more holistic education in the far reaches of the Himalayas. Kamar-Taj is technically not a boarding school for children...
