When is Film Art?

What kind of stupid question is that?  Film is always art.
Okay, now I'll give you my definition of art so that you don't get all fussed up about how some "bad" movie you saw wasn't art.  (And by the by, there are no "bad" movies, because in there is something good in everything, or else people wouldn't do it, now would they?)

Art is expression through creation.

Boom.  There it is.
So obviously, you create anything, if it means something, it's art.  Obviously a flim is art.  They're telling stories and they evoke certain feelings in the audience.  I cannot think of one common form of art that is absent from a film.
Fashion (aka costumes) say things about the characters and the setting
Notice the various cuts and styles of suits that James Bond goes through, or the suits in Tron
are you trying to tell me that's not art? it looks like a mix between a circuit board and a skeleton
Makeup (yes, guys, it is art - it makes girls 'beautiful')
  
 would the Joker have been as much fun without his makeup?  No, it's iconic.  All you have to do is draw some black eyes and a big red smile and people know it's this specific rendition of the Joker.

Sculpture (set, props) be they totally CG
  
or real things
 yeah, this is something between 'prop' and 'costume'
or this cave they built and filled with trinkets and tons of water for Pirates of the Carribbean

 Or Hogwarts???
Acting - duh.  Do I really need to explain how that is an art?  Good acting is not easy to do, folks, it's not just "the good guy is happy because it's the end of the movie and he just saved the world, and the bad guy is mad because his nefarious plan has been foiled"  No.  That's ridiculous.  We are not 2 year olds.

THE STORY- duhh, no one likes to hear a boring story

Writing! Prose, Poetry (the lines they say) - ever heard a moving speech that the leader of the underdog 'good guys' gives and it gets you all fired up and ready to kick some ass?  That's art.  Making words do that to someone is an art. 
For example the speech in Avatar that Jake Sully gives about how the humans don't own the planet, and they need to fight back.  I got so into that movie that I cried out of sheer epicness a couple of times....that is totally art.  The whole movie was an allegory (albeit with a happy ending) for what happened to the Native Americans at the hands of the white invaders, and also it sent a message to people that they need to value the Earth like the Na'vi value theirs.  (Note that the Earth is pretty much destroyed in this movie)  You telling me that's not art?
that movie makes more statements than this picture does...
Theater - I would say is the ability to combine words and acting and visuals and even sounds into something coherent and meaningful.

Music - Good music makes a great movie.  Imagine a horror film without the creepy, eerie music - it's less scary.  Imagine the movie Inception without the music - not as cool (but still really cool...)  What would Indianna Jones, or Pirates of the Carribean be without the exciting fight music?  Not as much fun.  Would Voldemort be as creepy in HP and the Sorcerer's Stone without his spooky theme music?  No, he'd just be some weird form of tumor.
 freaky yes, Dark Wizard of All Evil? Not so much.
The music from movies is so iconic and so ingrained in pop culture that we'd be lacking without it.  Darth Vader without the Imperial March? 

listen - you'll recognize them.
Music is one of the easiest and most powerful ways to give a movie it's aesthetic, and isn't that the most fun? 

Photography - Lighting and getting cool camera angles, filming stunts, that's not easy.  You've got to make sure that you can communicate the slowly burning fuse that's attached to some elaborate bomb contraption that's growing ever shorter while our hero is beating up some henchmen. 

Choreography - fight scenes, dance scenes galore!  First off, you have to make sure your fight scenes look real without actually dismembering your actors. 
Martial arts movies are a whole genre of flim based pretty much off of fight scenes and different styles of doing them.  Dance scenes in musicals have to be thought up by someone...and c'mon, they're just fun.  Also, coming up with new stunts for a film so they're not all the same.  The fight scens in the Matrix are something that even the majority of people will consider to be art.  There are some pretty creative ideas that are involved with making up a stunt for a movie. 
Youtube is full of videos of memorable stunts and movie fight scenes, I'm not going to look through them right now to find one for you because I'm sitting in the library and people will think I'm weird.

Putting it all together - With all these cool and exciting things you can do in a film, how do you put it together so that everything is balanced and that the film isn't all about one thing? That's an art too.  It requires lots of good judgement and the ability to say 'no' to things that are really very cool.

So, this whole rant was prompted by the assignment to read this article by Jesse J. Prinz (no idea who that is either) that explores how art relates to film and when do they overlap.  I think I've made it pretty clear where I stand, and hopefully, I've expanded your mind and entertained you.
