I am watching Quantum of Solace on my iPhone 5 (iOS 6.0.1), purchased from iTunes.
I noticed that the subtitles were in Spanish. I thought maybe the setting was wrong, but it was set to "Off". I then tried to switch the setting from "Off" to "US English", and now the subtitles disappeared.
So, "Subtitles: Off" gives me Spanish, "Subtitles: US English" gives me nothing.
Is it possible that the movie itself is messed up? All my other movies seem to be working fine, it's just this one, so I'm thinking it's not my phone.
Edit: A little further into the movie now, and the settings are back to normal. English is English, and Off is Off. But the first few minutes are still screwed up. I'm thinking it's a problem with iTunes.
