There's a documentary (2009, imdb link: http://www.imdb.es/title/tt1344315/) called "Garbo, the Spy" (Garbo was one of his nicknames). It's in spanish but i'm pretty sure there are english subtitles on the DVD.

This work won the Goya (Spanish National Cinema Award) last year for better documentary.

I read the article and thought: "At least, some british recognition to Pujol" :-)
