Contextual filter on a path alias
The issue is the following:

When you go to www.example.com/movies/star-trek-great/20130702 Drupal sees that this is a path alias to node/#, and it displays that node.  It won't use Views at all.

When you go to www.example.com/movies/Star Trek is Great/20130712, this does not map to any URL, but rather to the View sitting at www.example.com/movies with an contextual filter of Star Trek is Great (and 20130712 most probably).

You may have some other issues to work out as well:

Pathauto is taking out the is (and other small words by default) so there will be a bit of a hard time mapping star-trek-great to Star Trek is Great.  

Also, what happens if you have a title of Star Trek is Great!!! that maps to star-trek-great as well?
