NEW YORK(CBS) -- "The show must go on" is a phrase that may be as old as show business. But superstorm Sandy wasn't listening. Actually, a lot of shows are not going on.

Say hello to Hurricane Sandy which forced all 40 shows on the Great White Way to shut down saying "goodbye" to hundreds of thousands of dollars in lost revenue.

To stem the losses, "Spider-Man" and his friends really do need to "Turn Off The Dark." Variety senior editor Robert Hofler says, "Producers have to pay their staff, and the actors anyway, so it's really a complete loss for them."

For the second night, David Letterman showed up for the "Late Show" but played to an empty theater. And Jimmy Kimmel picked a bad week to bring his LA-based show to a very waterlogged Brooklyn.

But analysts are finding little to laugh about over Sandy's financial impact. "Person of Interest" and at least seven other TV shows that film in New York were told by the city they had to stop working and now facing the expensive process of re-juggling production schedules.

Paul Dergarabedian tracks the box office for Hollywood.com. He says that just like hundreds of jets on the East Coast, the big-budget movie Flight might be grounded on its upcoming opening weekend. While another film opening this weekend, Wreck-it Ralph, might get lift.

And how this for a Hollywood plot twist; the big budget Russell Crowe movie Noah about a biblical flood centuries ago had to shut down filming in New York because Sandy created floods that were all too real.
