All it took was an accent and some facial hair for Nathan Lane to get into the character of Gomez Addams for the new Addams Family musical on Broadway, which opened last night at the Lunt-Fontanne Theatre. The accent is “a little combination of Billy Crystal doing Fernando Lamas and Antonio Banderas doing the Nasonex bee,” he explained to us at the opening. As far as his new pencil mustache, he said it’s hard to maintain, but at least his friends like it. “They’ve seen facial hair before. It’s not, like, frightening.” They did call him on it, though: “[They said] ‘Is that an anchovy on your lip, or did you grow a mustache?’” See more in our Party Lines slideshow.
