Studying physics in Cambridge, Whitehead assisted Crick, Perutz and Kendrew. Trocchi helped run a pivotal poetry gig in London that he filmed (Shaffer giving him the money for the film-stock). Brook asked him to film an improvised Living Theatre piece, while Sternberg championed his film about the Rolling Stones. Saint Phalle collaborated on a film about sexual politics (described as disastrous), while Sinclair, suspicious about the reasons Whitehead was able to get away with as much as he did, made a film about the film-maker. Hughes, a friend, sent him a postcard poem about a falcon.
