SPARQL Query to get Movie detail

问题

To get movie detail from linkedmdb, I used sparql query :

PREFIX mdb: <http://data.linkedmdb.org/resource/movie/film>

SELECT DISTINCT ?Title ?Genre ?Actor ?Country ?Director ?Year WHERE { 
?film mdb:id ?uri . 
?film dc:title ?Title . 

?film movie:genre ?filmgenre.
?filmgenre movie:film_genre_name ?Genre .

?film movie:actor ?cast .
?cast movie:actor_name ?Actor .

?film movie:country ?Ctr .
?Ctr movie:country_name ?Country .

?film dc:date ?Year .

?film movie:director ?Drc .
?Drc movie:director_name ?Director

FILTER regex(?Title, "Kingdom of Heaven")
}

But SPARQL results shown Title same as counted Actor . How to combine the query so that Title is not repeated? I've try using GROUP_CONCAT but not working in LinkedMDB Endpoint? Could someone guide me?
