Broadway sales downshifted a bit last week, although two more shows joining the lineup helped keep the cume about on par with the prior sesh.New Frank Wildhorn tuner “Bonnie and Clyde” pulled in $265,147 for five previews, and Kim Cattrall starrer “Private Lives” rang up $51,250 for one perf; also contributing to the overall pot was previewing Alan Rickman starrer “Seminar” ($308,019), playing its first full frame of eight previews. Meanwhile, “Godspell” ($310,908) saw its box office rise despite having to accommodate comps for the show’s run of press perfs. None of those tallies rep gangbuster biz, but the new coin was still enough to help counteract the largely minor downticks at a number of shows. Most (but not all) productions logged slight downturns compared to the previous frame — including new B.O. buster “Hugh Jackman, Back on Broadway” ($1,173,785), although that one’s attributable to the fact that the show played one fewer perf last week than it had the prior sesh. Biggest falloffs were logged in the fluctuations of tourist-draw tuners “Mamma Mia!” (sliding more than $175,000 to $666,325), “The Phantom of the Opera” ($754,279) and “Chicago” ($457,708). One explanation for the Rialto’s downtick could lie in the Nov. 6 switchover from Daylight Saving Time — but while some legiters believe clock changes negatively impact B.O., others think that’s an urban legend. Also having affected biz was tight hotel availability due to the New York Marathon, not to mention the marathon itself, distracting tourists and Gothamites away from Broadway over the weekend. Jostling at the top of the chart led “The Lion King” ($1,579,280) to push “Wicked” ($1,535,611) out of its habitual seat at the head of the class. The still-rising “The Book of Mormon” ($1,370,277) continued to log the highest average price paid per-ticket ($156.50) on the Rialto, with “Jackman” posting a close second at an average of $149. Recently opened play “Chinglish” ($294,161), whose mixed reviews included its share of thumbs-ups, is still struggling to pull in auds, playing to crowds at about 55% of capacity. Sales at fellow play “The Mountaintop” ($697,502), however, remained fairly robust, while “Relatively Speaking” ($742,893), another play that opened recently, was one of the few shows that managed to climb last week. Main Stem cume slipped, just barely, to $21.2 million for 30 shows on the boards, with attendance rising slightly.
