"When in Toledo there I studied, It was my chance to write a tragedy - See here my lords - [He shows them a book] Which long forgot, I found this other day. Now would your lordships favour me so much As but to grace me with your acting it - I mean each one of you to play a part - Assure you it will prove most passing strange And wondrous plausible to that assembly."  
A haunted theatre these days is a perfect premise for a horror film.
