The return of co-creator and original star John Cameron Mitchell to “Hedwig and the Angry Inch” helped the Broadway musical post solid sales last week, a late-January frame when most productions on the boards slipped following the long-weekend boost of Martin Luther King Jr. Day.

Mitchell, who rotated into “Hedwig” after Michael C. Hall ended his limited run the prior week, originated the role of Hedwig in the musical’s Off Broadway premiere in 1998 and also starred in the 2001 movie adaptation. His appearance is a major draw for the cult of “Hedwig” fans, but whether that translates into an ongoing stretch of robust Broadway sales remains to be seen.

“Hedwig” played six performances and logged a healthy $609,618, or 93% of overall B.O. capacity. Attendance came in at 87%.

With all of Broadway bracing for a blizzard that threatened to cancel multiple performances this week, most of the Main Stem felt the chill last week, too. Overall sales fell $3 million to $21.3 million for 27 shows, and attendance sagged by almost 25,000 to 212,288.

Among the few titles to rise were Bradley Cooper starrer “The Elephant Man” ($1,035,819), back up to its full eight-performance schedule, and “Constellations” ($499,445), the Manhattan Theater Club production that stars Jake Gyllenhaal and Ruth Wilson and recently earned some prominent critical raves. Sting musical “The Last Ship” ($843,445) upticked, but just barely, in its final week.

Meanwhile, last season’s big-money hit comedy, “It’s Only a Play” ($462,008 for five performances), played its first shows in its new venue (after moving from the theater next door to make way for incoming tenant “The Audience”). It’s only in the coming weeks that box office watchers will get a sense of how the show’s sales will settle in now that its new cast members (including Martin Short) and its new theater have all fallen into place.

With the snowstorm, the next few days will probably be tough for the Great White Way. But there are bright spots ahead, most notably next week’s Feb. 2 start date for Larry David play “Fish in the Dark,” which has racked up a massive $13.5 million in advance sales and is poised to hit it big right out of the gate.
