Sister Act will clearly take a large house. The question is which one??
Theater(capacity) - current show - YES/NO(%)
Gershwin(1,933) - Wicked - NO(0%)
Broadway(1,761)- Promises, Promises. Only if the show bombs. Otherwise - NO(25%)
Palace(1,742) - West Side Story. Highly unlikely it'll close by the fall(or even spring 2011). - NO(2%)
St. James - American Idiot. Unless AI bombs - NO(5%)
Majestic(1,655 approx.) - Phantom - NO(1%)
Minskoff(1,621) - The Lion King - NO(0%)
Marquis(1,611) - Come Fly Away - Minsky's is rumored to want this theater anyway. - NO(20%)
Mamma Mia!(1,526) - Mamma Mia - NO(0%)
Lunt-Fontane(1,509) - The Addams Family. Even if it bombs, I still see it staying through the end of the year. - NO(5%)
Shubert(1,46

- Memphis. It'll be intersting to see how long Memphis will last - YES(75%)
Imperial(1,417) - Billy Elliot - NO(0%)
Neil Simon(1,362) - Love Never Dies - NO(0%)
Clearly it's best chance is the Shubert. After that maybe the Broadway Theater or Marquis(slim chances though). Sister Act may have to wait until spring 2011 if nothing opens up by the fall.
