Earlier this week, Insomniac were hosting an E3 panel about their new Spider-Man game. The show ended up being postponed, though, when audience members noticed that there was a small fire up on stage blowing smoke across the stage.
Turns out that one of the lights above the stage had caught fire, and so all official chat was postponed while crew tried to put the thing out. Here's some video of the delay (thanks Cody!) with Geoff Keighley looking on as people climb ladders.
