Can I say "By the way" in an official document or professional meeting and other important/formal times?

I never saw any film which would include these words.

No, I wouldn't recommend doing so, as the phrase is informal. There are many formal alternatives you could use to make you sound more professional, some of those are:

it is worth noting
it might also be noted/observed
