1 Too Late - You worry that it will, in fact, be finished. The set designer and builder suffer ulcers and/or sleep deprivation as the deadline approaches. Somehow though, the set is nearly always done for Opening ("How? I don't know, it's a mystery"). The audience smells wet paint.
2 Too Early - This means that you did in fact get 98% of your design built onstage looking 98% like you, the designer, hoped... but this gives everyone else in the production time to stare at the set and suggest tweaks. The audience smells wet paint.
Tonight is the opening for The Beauty Queen of Leenane. Great show - come out and see!
(And what do you think you may smell?)
