INSERT INTO actor_test VALUES( 108,'Stephen Baldwin');  
INSERT INTO actor_test VALUES( 109,'Jack Nicholson');  
INSERT INTO actor_test VALUES( 110,'Mark Wahlberg');

CREATE TABLE director_test (dir_id int not null unique, dir_name varchar(255));
INSERT INTO director_test VALUES(201,'Alfred Hitchcock ');
INSERT INTO director_test VALUES(202,'Jack Clayton');
INSERT INTO director_test VALUES(203,'James Cameron');

INSERT INTO movie_test VALUES(901,'Vertigo');                     
INSERT INTO movie_test VALUES(902,'Aliens');

INSERT INTO movie_test VALUES(909,'Chinatown');                     
INSERT INTO movie_test VALUES(910,'Ghosts of the Abyss');

CREATE TABLE mov_direction_test (dir_id int, mov_id int, act_id int,
FOREIGN KEY(dir_id) REFERENCES director_test(dir_id),
FOREIGN KEY(act_id) REFERENCES actor_test(act_id),
FOREIGN KEY(mov_id) REFERENCES movie_test(mov_id)
);

INSERT INTO mov_direction_test VALUES(201,901,101);
INSERT INTO mov_direction_test VALUES(203,902,107);
INSERT INTO mov_direction_test VALUES(204,904,104);
INSERT INTO mov_direction_test VALUES(203,905,107);
INSERT INTO mov_direction_test VALUES(206,906,106);
INSERT INTO mov_direction_test VALUES(203,908,107);
INSERT INTO mov_direction_test VALUES(209,909,109);
INSERT INTO mov_direction_test VALUES(203,910,107);

SELECT dir_name, act_name
FROM mov_direction_test md
LEFT JOIN director_test dr ON md.dir_id=dr.dir_id
LEFT JOIN  actor_test ac ON md.act_id=ac.act_id
LEFT JOIN movie_test mt ON md.mov_id=mt.mov_id
GROUP BY dir_name,act_name
HAVING COUNT(*)>2;

Sample Output:

dir_name     |act_name   |
-------------|-----------|
