And here we have . . . yet another movie musical releasing a trailer in which nobody sings. What are they hiding? Anyway, “Into the Woods” looks very pretty indeed, and any movie in which Meryl Streep plays a hissing witch and flings her hair around a lot is absolutely fine in my book. “Into the Woods,” based on a Musical In Which People Sing by Stephen Sondheim and James Lapine, will be in theaters for Christmas.
