Alan Ritchson is best known for playing Jack Reacher, an ex-military nomad who negotiates suspicious and dangerous situations. But in his new film, “Ordinary Angels,” Alan plays a father whose brawn is of little use in the face of his young daughter’s illness. Last year, the actor joined Tom Power to talk about playing a dad desperate to save his child, what it’s like to do a scene with an Oscar winner when you can tell she’s not sure about you, and why he wrote a letter to Tom Cruise when he booked “Reacher.”
