If you're looking to make an as-close-to-the-original title crawl as possible, you may want to look at LSText (

It's fairly low-tech, and takes some getting used to, but it will create a great looking crawl. It can even do the 'Star Wars' zoom at the beginning. Once you've made the parts you want, you can export them as .avi files and put them together in another program.
Here's one I made for a RPG a few months ago, to show you what it can do:

Or, if you're using a Mac, there's this nifty program that'll even create studio names. (

EDIT: An example of the Mac program is here:

Hope this helps.
