It doesn’t matter if you specialize in insurance, personal injury or petty naval law, Hollywood knows attorneys can do anything when the gavel starts pounding. We watched three movies about lawyers in way over their heads, fighting that good fight. Spielberg’s new “Bridge of Spies” pits Tom Hanks against an amoral Cold War world. “My Cousin Vinny” (1992) plays politely with New York and Southern stereotypes in a half-comedic courtroom. And “A Few Good Men” (1992) is novice Sorkin set in screamy military court with a dynamite cast. Now, call your first witness!
