Warner Bros. cut such a soaring initial tease for Bradley Cooper’s romantic drama/musical remake that we never got a second trailer. The stirring use of the two buzziest songs (“Maybe It’s Time” and “Shallow”) sells the film’s magical first act as a complete narrative. Yes, there are plenty of bits and pieces from the latter half of the film, but the teaser construction sets up the initial courtship between Jackson (Cooper) and Ally (Lady Gaga) as a standalone romance for the age, one which climaxes with the film’s centerpiece sequence. Sure, the rest of the movie can’t quite live up to that scene (which may be partially the point).
