This is great!  Can you please update the list to show each of the films directed by each director and keep the director names in the list?
SELECT T1.director ,  T1.title FROM Movie AS T1 JOIN Movie AS T2 ON T1.director   =   T2.director WHERE T1.title ! =  T2.title
show films directed by each director refers to JOIN on the same table with condition T1.director = T2.director; keep director names in the list refers to selecting director;
