Lacy Chabert, who played Gretchen Wieners in the original "Mean Girls" film, is starring in her 15th Hallmark Christmas movie. Talk about a "fetch" career trajectory! In "The Christmas Quest," an archeologist (Chabert) goes on a mission to track down the legendary Treasure of the Yule Lads in Iceland, trying to fulfill her late mother's lifelong dream. Joining her on the quest is her ex-husband (Kristoffer Polaha), who is an expert in the ancient Norse languages. "'The Christmas Quest' is a real adventure," Chabert said. "They go on this epic adventure together and perhaps work out some of their issues." "This is a movie both adults and younger people are going to love because there's the whole 'Indiana Jones,' 'National Treasure' aspect of it, but then, you've got these two adults who are dealing with ancient history, unfinished business," said Polaha ("The Shift," "A Biltmore Christmas"). "The Christmas Quest" airs Sunday, Dec. 1 at 8 p.m. ET on Hallmark Channel.
