BroadwayCon 2017 is going to be much bigger than its first year

Not even a blizzard could dampen the inaugural BroadwayCon, the theater world’s Comic Con, with enthusiasm so strong that organizers have lined up a much bigger show for next year.

BroadwayCon 2017 will take place Jan. 27-29 and has outgrown the conference rooms of midtown’s Hilton hotel and will spread out into the Jacob Javits Center for three days of performances, panels with the actors and creative teams behind the biggest shows past (among last year’s highlights was a “Rent” cast reunion) and present, singalongs, workshops and more.

Organizers have also revealed an early guestlist: This year’s unofficial con cheerleader Lena Hall is returning, along with Christopher Jackson (“Hamilton”) and con co-creator Anthony Rapp (“Rent”).

The event’s success has also drawn some new big names like Cynthia Nixon, best known for “Sex and the City” but a Broadway performer since age 14 who just made her Off-Broadway directorial debut with “Rasheeda Speaking.” Also onboard is Norm Lewis, who made history as the first black actor to portray the title character in “The Phantom of the Opera.”

The all-inclusive ticket — unlike most conventions, BroadwayCon’s price includes all autographs and photos with celebrity guests — remains a big ask at $600, but includes perks like reserved seating for all mainstage events, a special meet-and-greet, and guaranteed autograph and photobooth sessions. Single-day passes are still $95, while a three-day pass is now $250.

Tickets go on sale Monday, April 11, at 1 p.m.
