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)
improvededeede\" » improveededeede\" (Expand Search), improvedededeede\" (Expand Search), improveddeede\" (Expand Search), improvedeede\" (Expand Search)
improvededeedede\" » improveededeedede\" (Expand Search), improvedededeedede\" (Expand Search), improveddeedede\" (Expand Search), improvedeedede\" (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 improvededeede\\")) OR (\\"theatre improvededeedede\\"))\"".
• Removing quotes may allow a broader search: (( theatre ((improv OR improvede ) OR improvededeede )) OR ( theatre improvededeedede )).
