Milton is 78. Frugal, forgetful but not yet frail, the character, a retiree played by Ben Kingsley in the gently amusing and ultimately poignant dramedy “Jules,” regularly walks into downtown Boonton in western Pennsylvania (played by Boonton, N.J.) to complain at meetings of the town council: about the need for more crosswalks, or his proposal to change the town’s motto from “A great place to call home” to “A great place to refer to as home.” (The first wording is “confusing.” We get it. The members of the council look upon him with amusement, and so, dear reader, should you.)
