The Trial of the Chicago 7 is nothing if not a showcase for great performances. Writer-director Aaron Sorkin has his flaws – some of which are on display here – but one thing he does very well is creating the kind of punchy, snappy, rat-a-tat dialogue that good actors love to sink their teeth into. Some of that dialogue may not always sound natural – indeed, it often borders on speechifying. But Sorkin’s way with words, and a good actor’s talent for delivering those words, usually makes all the difference.
