As someone on a previous thread stated, Marian Seldes never missed a performance of DEATHTRAP, meaning that she was in 1799 consecutive performances...still a record.
Harvey Fierstein rarely misses and is known to admonish castmates for taking personal days.
Bernadette Peters never missed a performance of NIGHT MUSIC.
Sean Hayes only missed a handful of performances in PROMISES PROMISES, very late in the run. He said that his goal was to perform the entire run without missing a show, and he came very close to that goal.
Alice Ripley was known early in her career for never missing performances. That seems to have changed due to the vocal demands of NEXT TO NORMAL.
Similarly, Laura Benanti was known for poor attendance early in her career, but now she seems to have an excellent track record of late.
People who have been known to have attendance problems:
Fantasia Barrino
Emily Skinner
LaChanze
Chad Kimball
Katie Rose Clarke
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body
