I love open-captioned movies but the ones I go to are always half-empty, so for anyone who doesn't know:
CLOSE CAPTIONED means you need to request a special device to see the movie captions. It might attach to your seat. They won't be on the screen.
OPEN CAPTIONED means the captions are on the screen, like when you toggle them on your TV.
Lots of theaters do open captions but only for certain showings. If we all buy tickets to those showings, they'll do more of them.
