Airman, I'm pretty sure her TV appearances are over with (at least in the U.S.). King Arthur's been out for nearly a week now in the U.S., so I think it's a safe bet to say that she won't be promoting it anymore over here, and she won't have another film to promote until next year. Sorry.
In the U.K., however ... that might be a different story. KA won't be released there until the end of this month, so she may be popping up on variety entertainment shows and talk shows over there.
