The names mentioned should not be confused with similar names of other theatres in Berlin. The theatre is not identical to the "Theater unter den Linden" which operated from 1933 to 1945 in the former "Kleines Theater" at Unter den Linden 44; nor to the "Staatsoper Unter den Linden", the Berlin State Opera. Neither is it identical to the "Metropol-Theater" that operated in the former Admiralspalast from 1955 into the 1990s. Furthermore, today's "Komische Oper" has no connection to the "Komische Oper (an der Weidendammer Brücke)" which operated from 1905 into the 1920s as an opera theater, later as an operetta theatre, and finally as a revue theatre.
