Which famous filmmaker said "Self plagarism is style?"

Alfred Hitchcock, the legendary British director known for psychological thrillers like 'Psycho,' 'Vertigo,' and 'North by Northwest,' made this provocative statement about creative reuse. Hitchcock was known for recurring themes, motifs, and techniques across his films, and this quote defends his stylistic consistency as artistic signature rather than lack of originality. Spielberg, Lee, and Capra are directors but not associated with this quote.
