All you had to do is to search in google ''Films that were created at 1973''
after that it drops you a list of films.
then a hint with S letter film name's starting
you search letter S in the groups of all alphabetic letters,
and then copy a film name and post it into a Google's images.
if it doesn't work do like this : "[Films name] game"
HINT5:
http://en.wikipedia.org/wiki/List_of_American_films_of_1973 ;
HINT6: N-S;
HINT7: the film has the ''The'' at the film's name start, ex.: "The Film of Dark";
HINT8: Use Google's images.
If you really can't go through this, I will tell the name of this game
