Judy Greer was 'very nervous' around young co-stars on 'The Best Christmas Pageant Ever'

Direct a Christmas pageant? Judy Greer “would never do that.” But it’s a different story on-screen. Greer brings the mayhem in director Dallas Jenkins’ “The Best Christmas Pageant Ever,” where self-depracating Grace tries to wrangle disobedient kids to put on a community show for the holiday season. “I don’t even think I met them all,” Greer, 49, joked to The Post about her young co-stars. “There were so many kids. And that actually made me very nervous. I haven’t spent a ton of time with kids, but I have two step-kids. But they were older when I met them. They were 9 and 12 when I met, and there was only two of them instead of like 100, like in our movie.”
