Vacation is over, which means that moviemakers are back to work. Boston Police put out word yesterday morning that gunshots would be heard coming from Meadow Road in Hyde Park yesterday because of a film. We assume that’s the Ryan Reynolds movie “R.I.P.D.,’’ which has been using indoor space in Hyde Park for scenes. . . . According to the film spies at OnLocationsVacations.com, Sudbury actor Chris Evans is back at work filming “The Iceman’’ with Winona Ryder and Michael Shannon in Louisiana. The movie is about mob guy Richard “The Iceman’’ Kuklinski. Evans plays hit man Robert Pronge, a role that was going to be played by James Franco.
