In your ./config/routes.rb, you could do something like:
...
map.connect '/movies/:title',
:controller=>'movies',
:action=>'by_title',
:requirements=>{:title=>/[-_+.a-z0-9]+/i}
...
See Regular Expressions and Parameters on
http://api.rubyonrails.org/classes/ActionController/Routing.html for
more info.
