Looks like the low-budget, indie film “Fairhaven’’ is on its way. The movie, which is being helmed by Medford native Tom O’Brien, will start pre-production next week. Shooting will begin in January, which means that stars Rosemarie DeWitt (of “Mad Men’’ and the soon-to-be-released Boston film “The Company Men’’), Chris Messina (of “Julie & Julia’’), and Brad William Henke (of “Lost’’) will soon be around town.
