Ms. Tattersall concurred:
As a huge fan for decades of all comedies British that are regularly 
broadcast on the local PBS affiliate and BBC America, I'd come to 
believe that there really are only about fifty professional actors in 
Britain, because they all have been on most of the series at one time 
or other. Now they are turning up in the HP movies.
