According to Variety Sam Rockwell is negotiating to join Geoff Moore and David Posamentier’s Better Living Through Chemistry.
This means that Rockwell would replace Jeremy Renner in the role of an unhappy, small-town pharmacist who enters an illicit affair with a trophy wife (Garner) and begins to plot to murder her husband.
This was expected considering that Renner is attached to a Bourne reboot, a rally racing film, a potential Steve McQueen biopic, as well as a new Ice Age movie.
He might be replaced though by an excellent actor. And this maybe good for the movie considering the loss of someone like Renner. Also in the cast are Michelle Monaghan as Rockwell’s wife and Judi Dench as the story’s narrator.
