The English titles would be a welcome addition. 

Apart from nearly all of Bunuel's Mexican films, and some recent movies, the old titles at the Berlinale will be one Mexican, and three  Spanish  contributions from the 30s on which Bunuel had some input. I thought they were all Mexican - my mistake: 

Si usted no puede, yo sí  (Julián Soler / 1951 / Mexico) 
Don Quintín el amargao  "Don Quintin the Bitter" (Luis Marquina / 1935 / Spain) 
La hija de Juan Simón  "Juan Simon's Daughter" (José Luis Sáenz de Heredia, Nemesio M. Sobrevila / 1935 / Spain) 
Quién me quiere a mi  "Who Loves Me?" ( José Luis Sáenz de Heredia / 1936 / Spain) 

there will also be a Jean Grémillon film which Bunuel supposedly co-directed: 
¡Centinela alerta!  " Guard! Alert!  " (1937 / Spain) 

The complete Berlinale schedule is out by now, and you can also browse all titles by country.  

Which of the 100 listed films would you recommend, or which ones are available with English subtitles? I haven't anything specific in mind, as I have to catch up with the whole of Mexican cinema, of which I couldn't have seen more than half a dozen films, until now.
