This, the latest Bret Easton Ellis adaptation to come out of Hollywood, is making its premiere at Sundance this week. As with all Ellis adaptations, this movie has to toe a very tricky line, trying doing justice to Ellis’ stories of hard-partying, disaffected people while coming off as something more than empty hedonism. The closest a filmmaker’s gotten so far is Mary Harron with American Psycho, not just because she could confine herself to one character’s viewpoint but also because her constitutional inability to buy into the world Patrick Bateman was selling allowed her to find the satire. Alas, The Informers looks to be closer to the Less Than Zero approach, with Gregor Jordon turning Ellis into a cautionary tale for the ennui that plagues L.A.’s privileged classes. That said, the cast looks pretty solid- why shouldn’t it be, given the number of showy parts to be found in Ellis’ works?- and it’s always nice to see Billy Bob Thornton in a meaty role instead of simply playing one-dimensional weirdos or cops.
