Lou Castel did not receive an Oscar nomination for portraying Alessandro in Fists in the Pocket.
Now I write that it feels as a tiresome exercise because the whole plot setup feels a contrivance for a bit of dark storytelling about this family whom the majority of suffer from epilepsy with only the eldest brother capable of providing a living for his family. The youngest brother though decides to fix this that being Castel's Alessandro. That is the setup however this is not granted any true credence within the film. It is a motivation presented but not earned by what we actually witness within the film which seems built around just attempting to tell this story of a single son trying to destroy his family within. The film is more akin to say Chaplin's Monsieur Verdoux in its examination of these events with a certain callousness due to the focus being on Castel's Alessandro and his way of performing the part. The motivation, while granted as some false concern for his older brother, is left to be just the actions of a full blown sociopath however this is further emphasized by making this a stylized sociopath by Castel's portrayal. Castel seems to wish to evoke a young Marlon Brando with his work however he is more than few charisma points short for that coming closer to a precursor of sorts to Brad Dourif.
Castel's performance is quiet and intense as a proper Brandoian turn should be however he doesn't succeed in being that in any way. Castel fails to be charming being far more overtly creepy to the point that anyone should suspect him the moment anything goes wrong for anyone in his household. Castel grimaces around with a coldness that comes off as more off-putting than anything even before he starts to kill off his family members. His approach to stylize so much simplifies the part perhaps too much as even his claimed positive motivation seems a lie through his portrayal of Alessandro as so embracing of his life choices. Castel tries to be too cool for his own good even in this as he leaves the motivation to be thin finding no nuance in this. Instead Castel is content to depict Alessandro as this creeper throughout that I have to admit I found fairly tiresome fairly quickly given that give him scenes that seem to demand a more overt presence which Castel lacks. It seems as though the film would like Alessandro to be a more complicated figure to interpret however it is difficult to do so with his decidedly unpleasant work from the outset. There is no change within the character just this general petulant disdain that defines the man at all times, even his proclamations of love towards two of his siblings feel lacking given Castel's one note portrayal of the vile Alessandro. Although I would say Castel's performance could work within a different context it falters here given the greater importance given to his work. I will even grant him some credit for delivering in the epileptic seizure by throwing himself fully into the moment, but that is a minor point within the larger context of this performance. He needed to make Alessandro a far more dynamic force yet his "too cool for school" choices in developing the role leaves him a repetitious factor that simplifies the story to the point it becomes frankly boring despite its content.
