Looks like the publicity garnered by “The Phantom of the Opera” for its 10,000th perf a couple of weeks ago may be paying off: The 24-year-old Broadway stalwart saw sales spike last week, standing out in a frame that proved relatively healthy for most of the Rialto.“Phantom” ($985,906) was up more than $180,000, or 23%, compared to the prior sesh. Part of the bump may have come from the show’s performance on Monday, Feb. 20, catching the tail end of Presidents’ Day traffic, but with no cast shakeup or other change to grab attention, it seems likely the show also got a boost from the recent media coverage of its landmark run. Tuner saw by far the biggest bump in a week when the gains and losses were spread pretty evenly across the boards. Also adding to the overall Broadway pot were the robust sales for “Death of a Salesman” ($692,172 for seven perfs), the revival that broke a B.O. record at the Barrymore Theater in its second week of previews. Production turns consumer heads with a well-known title and a cast that includes Philip Seymour Hoffman and Andrew Garfield. “How to Succeed in Business Without Really Trying” ($823,986) also saw a notable rise, with the musical revival probably starting to benefit from the incipient cycle of academic breaks that can bring out the youthful fans of Nick Jonas, the production’s most recent topliner. “Stick Fly” ($449,964), meanwhile, got one final push of last-minute biz in its final frame on the boards, climbing 23% in the days prior to Sunday’s shuttering. Otherwise, some shows were up and some were down, with, for instance, a rise at “The Lion King” ($1,732,972) balanced by a dip of a similar size at “Sister Act” ($607,881 from auds that dipped under 60% of capacity). A number of shows held relatively steady, including recent addition “Shatner’s World: We Just Live In It” ($312,767). Overall, sales were up slightly, climbing about $245,000 to $20.3 million for 26 shows on the boards. Attendance was up around 7,000 to 217,156.
