For those who are curious like I was, this is Alberto Ammann who plays the main character, playwright Lope de Vega...

If it ever comes out in Brazil, check out "Celda 211". It's a very good movie and he and the great Luis Tosar are incredible in it and are both nominated for the Goyas on Sunday, so we'll see soon what happens, though while I do hope Ammann gets his trophy, I have to confess that Tosar's not my fave for best actor - as INCREDIBLE as he is in the movie, my heart is always gonna be with Ricardo Darín (nominated for Campanella's "El secreto de sus ojos", great great great great movie as well). What can I do, he's my fave actor, has been since "El hijo de la novia"...and is a very very cool dude too - I had the chance of meeting him a couple of years ago when he was at the Rio Int'l Film Festival to promote "La señal" and he couldn't have been nicer and sweeter (well, I guess Diego Luna was sweeter, but that's another story LOL).
Anyway, check out "Celda 211"! ;-)
