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)
improveeedeede\" » improveeeedeede\" (Expand Search), improvedeeedeede\" (Expand Search)
improvededededeed\" » improveededededeed\" (Expand Search), improvedededededeed\" (Expand Search), improveddededeed\" (Expand Search), improvedededeed\" (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 improveeedeede\\")) OR (\\"theatre improvededededeed\\"))\"".
• Removing quotes may allow a broader search: (( theatre ((improv OR improvede ) OR improveeedeede )) OR ( theatre improvededededeed )).
