Strong grosses for several shows pacing the field of Tony Award nominees — including Angels in America, Mean Girls and SpongeBob SquarePants — nudged the Broadway box office last week to a 4% increase over the prior week’s level.

Overall grosses for the week ending May 13 came in at $38,621,280, up from $36,994,027 in the previous week. The tally was up 15% over the comparable week in 2017. With two weeks remaining in the Broadway year, grosses to date stand just north of $1.6 billion, up more than 14% from 2017 levels. Attendance is ahead by just 1.6%, though, indicating that lofty prices are accounting for most of the growth.

The two-part Angels in America, which is the most-nominated play in Tony history with 11 nominations, had four performances of its first part, but just three of Part 2. Together, they pulled in $927,966 for the week, up 14% from $817,187 in the prior week.

Mean Girls, which tied SpongeBob with a leading 12 nominations, ticked up a fraction to a shade less than $1.5 million, from $1.46 million in the prior week. SpongeBob spiked 22% to $691,085.

Harry Potter and the Cursed Child, one of the commercial linchpins of Broadway this year, held steady at $2.1 million, a tally that should rise after the June 10 Tony Awards, after comps are reduced.

The Boys in the Band, which opens May 31, saw its grosses dip to $877,471 from $1 million the previous week after a minor injury to star Jim Parsons during the curtain call forcing the cancellation of one preview performance. Grosses A rep from the show confirmed that the show’s run of previews would resume Monday, as announced.

The crush of openings during the spring has passed. There were no new openings last week. And it marked the end of the commercial road for Lobby Hero, the starry revival of Kenneth Lonergan’s drama. It closed May 13, rising nearly 10% to $576,721 in its final full week.
