The kid’s ‘Room’

JACOB Tremblay ( above), the 9yearold star of Oscarbuzzed film “Room,” was fast asleep by the time the audience left a Crosby Street Hotel screening Wednesday. Then again, he’s been living in the fast lane. Now shooting his next film, with Naomi Watts, he’ll take a break this weekend for a Q&A at the Hamptons Film Festival. Costar Brie Larson arranged a Blade copter ride for him. Tremblay was overheard being asked at the screening, “Is this your first film?” “No, it’s my fourth,” he politely replied.
