Elf returns to Broadway for a holiday run with "Seinfeld"'s Wayne Knight as Santa Claus and Jordan Gelber as Buddy the Elf, a human raised among Santa's diminutive North Pole workers, who sets out to discover his true identity when he learns that he is not one of them. With an updated score from songwriters Matthew Sklar (music) and Chad Beguelin (lyrics), the production is helmed by Casey Nicholaw (who also serves as choreographer) and runs through Jan. 6 at the Al Hirschfeld Theatre.
