Try to ping your site after you made post. It takes less time to index your page if you do this every time you've made changes on your site.
Submit your website in social bookmarking websites.... Since google crawls them frequently you should get your crawl faster... Mark
If you're on google webmasters you can set the crawl rate. But make sure your site/server can handle it. You could also try to get your newest post crawled by placing a link to it on highly crawled sites like yahoo answers or ezine articles.
Once google index your pages, your pages are being cached . Actually as I know google(including yahoo) retrieve cached pages from archive dot org . ( I still don't know what is their relationship. )
You want early caching your site make sure update your home page every day and some collect quality back links everyday.
Google Webmaster Tools > Health > Fetch As Google > Add URL to data box > Click Fetch > When "Submit" button shows up in a few seconds, click Submit. I don't know of any faster way to let Google know you have a new or changed page that you want them to crawl. This is a hint Google's Matt Cutts gave (sorry, I don't recall the link).
Also, increase activity on your site with quality, it would give positive impact on crawling, indexing and ranking.
Hay, There isn't any such technique to make google index faster, it has its own work out on how and when should crawl and index websites. But if you want to get your new movie to be made popular I would suggest you two things. First is as soon as you upload anything new to your website, publish a Press Release on reputed sites likes SBWire.com or Prsync.com or PRlog.org, may be you can use some top 10 press release sits to submit. This would help you get your announcement on the internet and in many cases these Press Release gets listed fast on google news so in turn which would make your movie popular. Secondly you can use social shares like Facebook likes, Twitter tweets so get it more popular. I think this should help you more than enough. Remember we should solely depend on Google, we must have alternatives till google gets our site indexed and starts ranking them.
