The word "tentpole" is used to describe a blockbuster movie that can appeal to everyone. If it were applied to a festival, the Tribeca Film Festival would be it... "We're showing everything from an avant garde film called 'Passio' with live music by Arvo Part at the Cathedral of St. John the Divine--to 'Spider-Man 3,'" said chief festival programmer and executive director Peter Scarlet. "You can't get two things that are more unlike each other, but it's that almost surreal juxtaposition of different kinds of things that I think is an example of how we're trying to redefine what a film festival is."
