Perhaps you should try some spelling variations:
improv\" » improve\" (Expand Search), improved\" (Expand Search)
improveddedd\" » improveeddedd\" (Expand Search), improvededdedd\" (Expand Search)
improvededdedededee\" » improveededdedededee\" (Expand Search), improvedededdedededee\" (Expand Search), improvedddedededee\" (Expand Search), improveddedededee\" (Expand Search)
improvede\" » improveede\" (Expand Search), improvedede\" (Expand Search), improved\" (Expand Search), improve\" (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 improveddedd\\") OR improvededdedededee\\")) OR (\\"theatre improvede\\"))\"".
• Removing quotes may allow a broader search: (( theatre ((improv OR improveddedd ) OR improvededdedededee )) OR ( theatre improvede )).
