Best Man Wanted. Must Be Rush Fan

A man without a woman is like a pistol without a hammer, wrote Victor Hugo. But a romantic comedy without a female lead, well, that’s just a fine bromance and now Hollywood business as usual, as most recently demonstrated by “I Love You, Man,” a fitfully funny comedy that owes much to Judd Apatow, the king of such sublimated man-on-man affairs. Though Mr. Apatow isn’t officially credited, his DNA is all over this bromance, which stars Paul Rudd as a wuss who mans up by befriending a guy’s guy (Jason Segel) whose masculinity is so secure he wears Ugg boots and shorts to walk his wee dog.

Though he shares the soft-body profile of the typical Apatow hero — a gentle belly swell, the suggestion of an A-cup — Mr. Segel has butched up somewhat to play Sydney Fife, a surprising object of platonic affection for Peter Klaven (Mr. Rudd). The last time Mr. Segel appeared on the big screen was in “Forgetting Sarah Marshall,” in which he played the feminized hero, a man who cries over his broken heart.

In that film he’s so coded female that his new (female) love interest jokes, “I can see your vagina” when he balks at jumping off a cliff into the ocean. Here, though, it’s Mr. Segel who plays gender police and deploys the requisite gyno-joke by affectionately telling Peter to take his tampon out, guy-speak for chill.
