Two days ago W Magazine and The Film Stage posted a series of video clips in which several award-season headliners — Cate Blanchett, Paul Dano, Jennifer Jason Leigh, Jake Gyllenhaal, Alicia Vikander, Rooney Mara, Bryan Cranston, Benicio del Toro, et. al. — describe their favorite all-time sex scenes. HE’s favorite sensual intimacy scene is mentioned by Dano — that Notorious classic between a standing-and-fully-dressed Cary Grant and Ingrid Bergman when they’re more or less glued and never stop kissing and nuzzling. HE’s all-time favorite sex scene is the one between Tom Cruise (by anyone’s measure an unlikely participant in this realm) and Rebecca DeMornay in Risky Business. It’s perfect because like any transcendent sexual encounter it feels levitational — orchestrated, finely tuned, rhythmic, musical. It multiplies and compounds the sexual train metaphor that Alfred Hitchcock created in that last shot in North by Northwest, and it ends with that perfect (i.e., very subtle) electric train-track spark.
