Well, this is unexpected. Just one day after releasing 10 new images, and an hour after posting about them, there's a teaser, too.
You'd think they'd want to space out the media attention since Christmas is still a long way away but we'll take it. As per usual, they're not quite admitting it's a musical yet in advertising. You hear the opening words "I wish..." of the prologue chorale number over and over again but nobody quite sings it as if the spirit of Rex Harrison has taken over. Anna Kendrick comes closest to sounding melodic while just speaking. But the teaser is enticing.
Come what may, for better and we-hope-not worse, it will be an event to see this musical on big screens during the holidays.
