Comic-Con: Superheroes of Varying Sizes and Shapes

SAN DIEGOâ€"Who was that masked man?

Maybe, just maybe, Jack Black.

According to a publicist for the Yahoo Web series “Ghost Ghirls,” Mr. Black, one of its producers, spent Thursday morning wandering the halls of the Comic-Con fan convention here, disguised in a Nacho Libre mask. That would be the identity-concealing, Mexican-wrestling mask he wore in playing the good-hearted title wrestle of the 2006 comedy “Nacho Libre.”

On the one hand, it might have been possible for the sharp-eyed to spot Mr. Black via his physique, which resembles that of the Pillsbury Doughboy. On the other hand, the halls are being stalked by a lot of masked nerds who are similarly shaped.

Amanda Lund and Maria Blasucci, the two deliberately dizzy blondes who star as clueless ghostbusters in the comic series, had some fun with the general doughiness. “Boys who like superheroes sometimes look like superheroes,” one of them deadpanned from the stage at a presentation of the series. Then they looked into the crowd for an example.

And looked. And looked.
