Jean Renoir's LA CHIENNE is an exhilaratingly nasty tale of a henpecked hosiery cashier's adulterous relationship with a manipulative prostitute, and the moral damnation that ensues. Noir aficionados will instantly make the SCARLET STREET connection but the unmistakable differences in execution and style render both of these masterworks sufficiently distinguishable.
Firstly, LA CHIENNE is more sexually charged of the two - evidenced by the explicit exhibition of its various on screen dalliances. SCARLET STREET on the other hand was shackled by the Hays Code where the furthest Edward G. Robinson's character gets is painting his mistress' toe nails. Restrictions of the production code notwithstanding SCARLET STREET is still the bleaker of the two and remains one of the hallmarks of classic film-noir, while LA CHIENNE benefits from its consistent tragicomedy tone.
Michel Simon is outstanding as the frustrated, love-struck painter who's almost destined to lose: he's domineered by his miserable wife when he's not being cuckolded and scammed by his deceitful mistress (and her scheming pimp boyfriend) and remains oblivious of the fact that he's merely a part-time lover but a full-time benefactor. EGR's rendition however was on a completely different level and had more psychological heft to it.
LA CHIENNE's visual aesthetic is loaded with quadrangular, window-framed, canvas-like compositions that not only resonate with the film's theatrical opening but also with the art produced by our protagonist. I also feel that it's too beautifully realised (or at least the restoration made it so) to be categorised as "noir" in the traditional sense and is devoid of conventional noir flourishes, rugged edges or pulpy vibes. Having said that it was undoubtedly instrumental in the proliferation of films that would come to be known as noir.
As an interesting aside, SCARLET STREET was not the only Lang venture that shared a literary source with a Renoir film; HUMAN DESIRE and the classic LA BÊTE HUMAINE also originate from the same Émile Zola novel.
