Samuel Goldwyn Films has taken U.S. theatrical rights to Geoff Moore and David Posamentier’s “Better Living Through Chemistry,” the dark comedy that stars Sam Rockwell and Olivia Wilde.

Goldwyn has cued up the film for a spring release, with homevid distribution in the US to be handled by Universal Studios Home Entertainment and Universal Pictures Intl. Entertainment taking care of ancillary platforms in the U.K., France, South America and other territories.

Plot of “Better Living” centers on a pharmacist (Rockwell) whose life gets wild when he begins an affair with one of his customers (Wilde). Michelle Monaghan, Norbert Leo Butz, Ben Schwartz, Ken Howard, Ray Liotta and Jane Fonda also appear in the pic, which Moore and Posamentier co-wrote and co-directed.

Occupant Entertainment’s Joe Neurauter and Felipe Marino produce with a team that includes associate producers Richard Naing and Kate Sharp and exec producers Keith Calder, Anders Erden, Graeme Law, Peter Nichols, Posamentier, Tim Smith and Paul Brett.

Distribution deal was pacted by Will Machin of Metro Intl., which handled international sales for the film, and ICM’s Jessica Lacy.

The film from Occupant — the production company currently at work on Sophie Barthes’ Mia Wasikowska-toplined take on “Madame Bovary” — joins a Samuel Goldwyn roster of upcoming releases that includes doc “Anita” and Naomi Watts starrer “Sunlight Jr.”
