Alan has given us a bit of homework today, to look into 'thirds' of the film / games worlds. Heres two quick examples I have found so far.
This first example is from Final Fantasy 3. The Characters are very clearly in the 3, thirds of the screen. The character in the middle is bigger and stands out a slight bit more than the other two characters.
This next example is from Saw VI (Hmm.. 6), and doesnt really show the thirds that well but from what I can make out, top middle square has the foreground characters' head in it, the middle section of thirds. And the background character is taking up the lower right portion of the screen.
I shall look into a few more and upload at a later date. ;)
