Screenwriter and producer Thomas T.S. Cook, best known for penning the 1979 thriller The China Syndrome died Saturday after battling cancer. He was 65. Cook, a Cleveland, Ohio native, received Oscar, BAFTA and Golden Globe nominations for Best Screenplay for The China Syndrome, an honor he shared with co-writers Mike Gray and James Bridges.
