Just to add something to this, I've found that people have a general dislike of the poster image forcing the first gun's text to the left of the page, and tend to do it like this:
Quote:
[[Poster_image.jpg|thumb|right|400px|The Title]]<br><br><br><br>etc
|
Thing is, this forces the table of contents down too, and this doesn't look great; if the movie's poster image is big, the table can be forced right down so it's barely on screen when the page loads. Here's a better way:
Quote:
[[Poster_image.jpg|thumb|right|400px|The Title]]__TOC__<br><br><br><br>etc
|
That's two underscores either side of "TOC." This forces the table of contents to appear before the new line breaks, on the same line as the poster art. The difference is the first gets you
this while the second gets you
this.
