Susan Sarandon, who’s 65, and her 34-year-old boyfriend Jonathan Bricklin hit the Grand Classics screening of “Midnight Cowboy” at the W Downtown Thursday. Guests including host Spike Lee headed onto the balcony at the pre-flick cocktail party to watch the darkening sky. Sarandon, who’d been taking photos of the oncoming storm with her phone, dropped it once the downpour started. Hotel security rescued it, prompting her to exclaim, “You’re my knight in shining armor.”
