Perhaps you should try some spelling variations:
improv\" » improve\" (Expand Search), improved\" (Expand Search)
improvede\" » improveede\" (Expand Search), improvedede\" (Expand Search), improved\" (Expand Search), improve\" (Expand Search)
improvededdeede\" » improveededdeede\" (Expand Search), improvedededdeede\" (Expand Search), improvedddeede\" (Expand Search), improveddeede\" (Expand Search)
improveedededede\" » improveeedededede\" (Expand Search), improvedeedededede\" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"theatre ((improv\\" OR improvede\\") OR improvededdeede\\")) OR (\\"theatre improveedededede\\"))\"".
• Removing quotes may allow a broader search: (( theatre ((improv OR improvede ) OR improvededdeede )) OR ( theatre improveedededede )).
