A film about a ghost horse out West who is guarding a long lost hidden treasure.

I don't know much about what makes a western film a western film in a script, since I basically find an idea and work my way with it during production, but I do know that the editing and voice acting can help a lot. When you get voice actors, be sure to ask them to try and produce a 'western accent'. This will most definitely make the view seem like they're watching an actual western.

For during production, a well attribute to add is a tumbling weed out in the distance. Don't get lazy and put in your film what you have. If you don't have, for example, a cowboy torso, make a decal or even find one. Maybe even a scarf (as seen in this photograph).

In post production, I highly recommend you find dust particles to edit in afterwards. If you are willing to put in the effort of all this, I bet you will come out with a professional looking project that I can't wait to see. Hope this helped in the stages after pre-production!

Mason - I like the decal idea, of course I'm not rich, like I said.  And I'm not a fan of asking for money so decals could be the way to go.  Also, on your recommendation for dust, yes, I do think it's important that I have dust in some scenes, however this isn't a sandstorm so I want to keep it realistic.  Voice actors, yes, I might get people from BiM to do some of this, but I'm hoping that I can get people at my local A/V Club to voice act because I'm pretty lame at voice acting.

BWJC - Maybe My Little Pony should have a short sequence.  Nay.  But yes, I'm going to talk over characters and story (Which is the hardest part) to make this an original film.  As for the small but important details, thanks!  You answer my topic of "What makes a western a western".  That's what I wanted.  Although do you think gold mines should be included in this?  Because what were these bandits always after?  Money.  So bars, pubs, and gunfights would be a very important element.

To Readers - I don't want ghosts since Vande is making "Ghost Town".  So I need to base this on real life.  Not real life events but I want a realistic fantasy.  So if anyone has to know any article I can read about western bandits then it would be helpful.

It helps to spend some time watching live-action westerns. I'm pretty sure Doug got inspiration from some to make America: Outlawed.

My western brickfilm borrows aspects from a lot of well-known westerns; such as revenge, greed, etc.

Some suggestions: Once Upon a Time in the West, The Magnificent Seven, Hondo, Red Dead Redemption

Shanghai Noon.

Yes, I mean that. I loved Shanghai noon.

I've never actually seen a "proper" Western film before. He he
Only things I have seen are things like Back to the Future Part 3, Rango, and random scenes from other movies and TV shows which play on it.
I'm probably not the best to ask. xD
(BTW Rango is an amazing movie, seriously.)

Though, I do have an idea for a Western brickfilm that I may make eventually called "Italian Standoff: a LEGO Spaghetti Western" which is basically filled with parody and really random weird humor.
Regardless of that, I still want it to have a good Western story, so I'm sort of wondering the same thing. xD

Do you need me to help with the plot? I'm great with stories.

Mmm... I'm probably not the best for Western names...
I had a Western styled bad guy in How to Not Rob a Bank, his name is Gohgzvoqsterwazootuli. I don't think you'd like a name like that. xD

I'd suggest taking some name which doesn't really sound extremely cool on its own, but add in a nickname with it.

Like "Stinky Clive" Or "Clive the Bull"

Okay, those are very bad bad examples, but you could come up with some cool names with that.

I particularly liked the name of the bad guy in Rango "Rattlesnake Jake" Which isn't exactly a nickname since he is a rattle snake, but it sounds like one. xD
