Broadway grosses got a nice boost last week, in a healthy bump legiters attribute in part to the celebrating families in town for the weekend’s slew of academic graduation ceremonies.

Eight shows made the frame’s millionaires’ club, with “How to Succeed in Business Without Really Trying” ($1,057,840) and “Priscilla Queen of the Desert” ($1,028,470) among the tuners stepping up to join.

Also notably on the rise was play “The Motherfucker With the Hat” ($736,699), which overcame early-perf marketing challenges to snag strong reviews, awards momentum and sales that made it the the week’s second-highest grossing play on the boards, behind consistent strong-seller “War Horse” ($897,133) and within spitting distance of splashy tuner “Catch Me if You Can” ($753,988).

“Spider-Man: Turn Off the Dark” ($1,260,794) returned to eight-perf weeks playing to 95% of capacity, which indicates there’s still interest (for the moment, anyway) in the ongoing evolution of the big-budget comicbook tuner.

But just a rung below it on the Top 10, “The Book of Mormon” ($1,148,314) seems to be benefiting from the high demand prompted by a skyrocketing profile and a smaller venue that seats almost 900 fewer theatergoers than the house occupied by “Spider-Man.”

As is usually the case in frames when visitors come to town, it was the big-title tuners and family shows that posted the larger gains, although “Mary Poppins” ($771,761) was left out thanks to a couple of regular perfs nixed to accommodate a private event.

With almost every single show on the rise, overall Broadway sales climbed about $1.9 million to $24.9 million for 35 shows on the boards.

Still, in a crowded, competitive season, some shows had trouble drawing sales, particularly among plays. Revivals “Born Yesterday” ($288,933) and “Arcadia” ($213,594), for instance, played to capacities of 55% and 47%, respectively.

Among other non-tuners, “Lombardi” ($295,781) played its final frame, while “That Championship Season” ($512,454) preps for its May 29 closing.

With Memorial Day weekend repping the imminent kickoff of summer, a number of Broadway shows can look forward to logging the robust sales the warm-weather months generally bring to the Rialto.
