Robert De Niro and his producing partner Jane Rosenthal started the Tribeca Film Festival to revive New York after 9/11 -- and eight years in, they're at a turning point. This year's festival is scaled back somewhat, and yet, this is a time of growth for TFF. When I asked them what stage the TFF is at now, they said it's no longer a baby. "I feel we can walk now," Rosenthal told me. "We've gotten our footing, to use that analogy."
