Two thoughts occurred while watching the Broadway revival of Terrence McNally's Frankie and Johnny in the Clair de Lune, which opens Thursday night at the Broadhurst Theatre (booking to Aug. 25). Why couldn't this have opened a few weeks ago and been eligible for the Tony Awards? It would have been a strong contender for Best Revival of a Play, and its two stars, Audra McDonald and Michael Shannon, likely contenders for Best Actor/Actress in a Play.
