Superman's night: If you are the type to brave the Montauk highway early (and to pay for your hobnobbing), the Christopher and Dana Reeve Foundation has its annual summer benefit in Sag Harbor, with Reeve family members, the rascally Alec “no more cell phones” Baldwin, sultry Kim Cattrall, skinny Sarah Jessica Parker and pleasantly plump Matthew Broderick. Back on the island, Radio City Music Hall hosts the premiere of the motion picture Live Free or Die Hard, which asks the question: Why oh why does Bruce Willis never age? Why, he looks younger than Ashton Kutcher! Mr. Willis will be in attendance as well as co-stars—and hotties—Timothy Olyphant (he made moustaches sexy in Deadwood) and Maggie Q. See—even the big shots get stuck in the city on a summer weekend sometimes!

[The Christopher and Dana Reeve Foundation’s Third Annual Summer Solstice Celebration, B. Smith’s, Sag Harbor, 7 p.m., www.christopherreeve.org; Live Free or Die Hard, Radio City Music Hall, 1260 Sixth Avenue, 8:30 p.m., by invitation only.]
