This is an excellent little film, which shows Renee Zellweger at her delightful best opposite the commanding Vincent D'Onofrio.
Apparently, it was shot in only 24 days, & this shows perhaps in the exterior shots, which have to stand in for all the seasons over about a 3 year period.
However, our interest is firmly on the characters & their on-off love affair. There are one or two moments of 'magic realism' (the wolf, Howard as Conan etc) which add an almost supernatural feel to what is basically a low-key, socially-realistic presentation of 30s Texas, & which likewise occasionally counterpoint the somewhat cliched romance narrative.
The book from which the screenplay came, One Who Walked Alone by Novalyne Price Ellis, is also a great read!
