I'm a bit surprised. I've never seen the play, but if Lew is right and it's even better than the film, I hope to see it some day, because I find Barefoot in the Park to be a great movie.
I'm not sure which is greater. The number of films that Edith Head was designer for, or the number of classic Hollywood films from the Golden Age that Brook hasn't seen. Though to be fair, for every such film he hasn't seen, he has seen two obscure films in Farsi or Tagalog or some such language.
