How do I write transitions between thinking and speaking?

Question

I've just downloaded an open-source script-writing program, and have started converting the scripts for an anime I've been writing into industry-standard formatting.

There are a few points in the scripts where a character says something out loud, then immediately thinks something else (which the audience hears in voiceover), or thinks something and then says something else out loud. In my (not-at-all industry-formatted) scripts, I've indicated these like so:

CHARACTER: Follow me, and stay quiet. We'll be out of here shortly. (in thought) I hope.

Or:

CHARACTER: (in thought) This isn't good. (out loud) Guys, we need to get out of here now--

I already know that I need to change "(in thought)" to "(V.O.)", but other than that, how do I convert these into industry-standard formatting?

Answer 1

Using V.O. for the thought parts should be sufficient. Eventually, you can also add the word "thinking" or similar in parentheses for that piece of dialogue.

For example:

          CHARACTER
     It sure is nice to speak out loud!

          CHARACTER (V.O.)
        (Thinking)
     Though thinking is actually even better.
