CaptionFish!

If you are looking for captioned films, you can visit Fomdi.com and type in your Zip code, and the site lists theaters and their offerings near you. Or you can visit individual theater chain sites (like Regal, AMC, etc.) and try to find the sole captioned film playing (if any are playing).

Now there is an even more coherent and visually pleasing site that rounds up all your nearby options, called CAPTIONFISH.COM.
