The Tribeca Film Festival now is celebrating its 15th year and founders, actor Robert De Niro and producer Jane Rosenthal mark the occasion with an interview on TODAY. De Niro, who has an autistic child, comments on the decision to pull the anti-vaccination film “Vaxxed” from this year’s lineup, even though he says, “I think the movie is something that people should see,” and he questions statistics on vaccine-preventable diseases.
