She's left the Abbey for the skies in her new thriller Non-Stop, and Michelle Dockery, who plays a flight attendant in danger, couldn't have been more thrilled to work with A-list co-stars Liam Neeson and Julianne Moore.

"It was amazing to work with [Liam]," the Downton Abbey star raved about the Irish actor on Chelsea Lately. "And you know, he's such a nice guy. But he is, he's huge," she said of Neeson's imposing size.

"I don't think I've ever seen him in person," responded host Chelsea Handler. "Yeah he's massive," Dockery replied.
