Pere Portabella was a great and highly original Spanish filmmaker. His films No compteu amb els dits, Nocturno 29 (Nocturne 29), Cuadecuc, vampir, Umbracle, Pont de Varsòvia (Warsaw Bridge), and Die Stille vor Bach (The Silence Before Bach), have been fundamental links of an alternative and influential film culture. As a producer, we owe him Marco Ferreri’s El cochecito and Buñuel’s Viridiana. Portabella has also been a relevant politician: he was elected senator in the Spanish Constituent Cortes and his signature is on the 1978 Spanish Constitution. Constel·lació Portabella is developed from fragments of his own films and debates, conferences and interviews with Portabella himself in different media throughout his career as a filmmaker and politician. Framing all this are twelve interviews with critics, directors, and film and art historians who have dealt with his work or participated in its creation. Thanks to them, we can penetrate into the challenges behind Portabella’s creative choices.
