Elections (Alexander Payne, 1999), 11pm on BBC Three
Ferris Bueller (aka actor Matthew Broderick) is an adult in this film directed by The Holdovers Oscar winner Alexander Payne. Now, instead of being a truant, he’s Jim McAllister, a history and civics teacher at a Nebraska high school, but still a misfit for valedictorian and Type-A terrorist Tracy Flick. When Fleck — played by Reese Witherspoon in a career-defining performance — runs for student president, McAllister sets out to sabotage her campaign, turning in a sharp satire of political power plays.
