"It is pretty nice," he smiled, accompanied by his parents and a publicist. "We tried a few ones and this one was pretty cool. I like this one a lot."

He wasn't kidding. Pret-a-Reporter spotted Tremblay posing for fan photos on the red carpet around 11 p.m., following one major party stop at the Warner Bros./InStyle party inside the Beverly Hilton. He looked tired and ready for bed. "He's running out of steam," relayed his mother. 

There's plenty of steam left on the Internet for Tremblay's dad, who works as a real-life police detective. Whoa.
