Okay, I've tried this two ways:

redirect 301 /reviews/plan9fromouterspace.shtml http://www.scifiblock.com/movie-reviews/plan-9-from-outer-space-1959.htm

and

RewriteEngine on
RewriteRule ^/reviews/plan9fromouterspace\.shtml$ movie-reviews/plan-9-from-outer-space-1959.htm [R]

And neither work. The former returns http://www.armoredsquidbrigade.com/movie-reviews/plan-9-from-outer-space... (which is PAGE NOT FOUND)

The second one just does not redirect whatsoever.

Is is safe for me to post my .htaccess file? If so I'll provide a pastebin link. Otherwise, any ideas why it's not working? I'm using Bluehost, and I did notice that within my root, I can go to C:\WINDOWS\Temp and there is another .htaccess file there with just three short lines of code. I'm guessing I shouldn't mess with that one.
