If one is over 18 or can figure out a way to lie about their age and peg it to a phony email account, the new red-band trailer for For a Good Time, Call… (Focus, August 31) is online now, over at YouTube. The trailer sells the concept and nicely spotlights a few naughty bits, but, having seen the movie, I can say it doesn’t fully get at and convey the effervescent charm and chemistry of Lauren Anne Miller and Ari Graynor, which is its true strongest selling point.
