John Le Carré said this quote

His intuition was luminous from the instant you met him. So was his intelligence. A lot of actors act intelligent, but Philip was the real thing: a shining, artistic polymath with an intelligence that came at you like a pair of headlights and enveloped you from the moment he grabbed your hand, put a huge arm round your neck and shoved a cheek against yours; or if the mood took him, hugged you to him like a big, pudgy schoolboy, then stood and beamed at you while he took stock of the effect.
