Launching the biggest show in the history of Broadway can't be easy – especially at a time when the Great White Way has been having a particularly rough go of things. But after years of delays and financial troubles, the makers of 'Spider-Man: Turn Off the Dark' are forging ahead with the mega-musical, whether it's ready or not.

Directed by the visionary behind the Broadway reimagining of 'The Lion King' and with a full-length score by two of music's most iconic figures, Bono and the Edge from U2, 'Spider-Man' is as big a risk as has ever been undertaken in theater, and the stakes are high, according to '60 Minutes': "The danger and risk with 'Spider-Man' the musical is that to stay afloat, to keep running, it has to be as big a hit as Broadway has ever seen."

Despite being pushed back repeatedly over the last several weeks – the show's first planned preview was set for Nov. 14, after having already been delayed from January and February of this year by longstanding production issues – and following word from sources close to the production that it was far from finished, the first preview performance of 'Spider-Man: Turn Off the Dark' went ahead on Nov. 28, but it was far from the flawless spectacle Bono, the Edge and director Julie Taymor likely wanted. Instead, the production had to be stopped five different times to fix technical problems, causing its running time to bloat to just under four hours.
