Will "the real Liam" stand up? Liam Neeson and Julianne Moore talk up their new airplane thriller Non-Stop, in theaters today, and Julianne explained to ET that her daughter got excited about the fact that her mom was working with Liam -- albeit the wrong one; she thought her mom was working with Liam Hemsworth!

"I thought that was pretty funny," laughs Julianne. "See, there's a Liam for every generation."
