Film pick: Dirty Harry

Maybe Clint Eastwood's Harry Callahan would have had more faith in the justice system and been less likely to go off on vigilante tangents if he was busting crime in these days of DNA and other CSI technology. Just ask Amy Brodeur, assistant director of the Biomedical Forensic Sciences Masters Program at Boston University School of Medicine, as she screens and discusses Don Siegel's Dirty Harry (1971), the first outing for the legendary lawman. It's part of the Coolidge Corner Theatre's Science on Screen series. The Coolidge is at 290 Harvard St, Brookline | 7 pm | 617.734.2500 or coolidge.org.
