Casey Sherman (born January 19, 1969) is an American author, journalist and screenwriter most famous for his 2009 novel The Finest Hours.
Sherman was born in Hyannis, Massachusetts. He attended Barnstable High School and graduated from Fryeburg Academy in 1988. He studied at Boston University, graduating in 1992.
As a television news producer for WBZ-TV, Sherman led a high-profile re-investigation of his aunt's murder, which he later chronicled in his 2003 book, A Rose for Mary: The Hunt for the Real Boston Strangler. Sherman's work suggests that his aunt, 19-year old Mary Sullivan, might not have been a victim of the Boston Strangler, as commonly believed.
Sherman wrote The Finest Hours in 2009, co-authored with Michael J. Tougias. The book was developed into the 2016 motion picture of the same name. It was filmed in Quincy, Massachusetts and Chatham, Massachusetts for Walt Disney Pictures. The Craig Gillespie-directed film stars Chris Pine, Casey Affleck, and Eric Bana.
Sherman's other books include Animal: The Bloody Rise and Fall of the Mob's Most Feared Assassin, Bad Blood, Black Irish, Black Dragon, and Boston Strong: A City's Triumph Over Tragedy. The latter, about the city's response to the Boston Marathon bombings, was adapted as a feature dramatic film, Patriots Day (2016), starring Mark Wahlberg and directed by Peter Berg.
