I’ve often recommended the novel My Sister’s Keeper as an interesting exploration of what the British call savior siblings — using reproductive technologies and preimplantation genetic diagnosis (PGD) in order to have a child that can be an organ or bone marrow donor for an ailing sibling.
On June 26, the movie version opens, starring Cameron Diaz, Abigail Breslin, Alec Baldwin, and Sofia Vassilieva. I wonder if they’ve changed the ending?
