There has always been something intriguingly wholesome about Jennifer Garner, which she has never shied away from when choosing roles. She has been the little girl trapped in an adult’s body (13 Going on 30), the aspiring adoptive mother (Juno) and the love interest capable of redeeming the impossible horn-dog (Ghosts of Girlfriends Past). But in The Odd Life of Timothy Green and her latest, Miracles from Heaven, Garner dives headlong into modern faith-based tales of saintly mothers confronting miraculous confirmation of their beliefs. The real revelation in director Patricia Riggen’s account of Christy Beam’s book is that an industry that believes only in the hard proof of box office receipts would join Garner in these leaps of faith.
