That's an unfortunate, sad story.
However, in situations like this where you might have some legal leverage, it never hurts to attempt some sort of negotiation. He could, for instance, negotiate himself into some sort of production position in the upcoming shoot or on some other set.
This is going to sound really harsh: Aside from nepotism and sheer luck, people do really make it in the film industry based on pure will and this could have been his opportunity. However, in the end he murdered his darling and packed it in. With an attitude like that (harsh, I know) his chances were slim. The film industry is not a meritocracy, and his art alone would not have carried him to success. He needed to hustle, in both senses of the word.
If he did try something like that, then I feel doubly worse for him, though.
