I had to fix Jakes eyes as he was looking at the camera the entire take, and this was the only coverage I had as a close up. It ended up working out anyway and just as a test I added the text of what he was saying.
One of the things I've noticed is that the dialogue cards tend to interrupt the flow of the scene a little. Most times, it's ok. But having subtitles of a sort helps out with that, if they're creative!
