The world premiere of “Fairhaven” at the Tribeca Film Festival should help New York theater actor Tom O’Brien check a few items off his bucket list. Not only is it his first film festival experience, it’s also his first time writing, directing, and acting in a feature film. “These guys really love their films and are passionate about what they do,” O’Brien says of the fest’s programmers. “I feel so grateful and lucky to be in the Tribeca Film Festival. It still doesn’t seem quite real. I honestly don’t think I would ever premiere a film anywhere else after this experience.”
