Jim Carrey stars as a dogcatcher who becomes obsessed with the numerological implications of 23, seeing it everywhere (if not the digits themselves, then in sums or the numeric values of letters and months) and eventually unnerving his wife (Virginia Madsen, in her latest sturdy-spouse role). Narrated in voice-over by the hero, the movie is an object lesson in the dangers of having a storyteller who manufactures his own logic. As Carrey becomes more engrossed in an obscure novel about the number, this balloons into a murder mystery with multiple layers of reality, and before long I wasn't even sure what might constitute a conclusion. Joel Schumacher directed; with Danny Huston. R, 95 min.
