The full name of the movie often called "Dr. Strangelove" is Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb.
I find it odd that there is a colon after a conjunction like "or." Is that correct usage in a ordinary sentence (i.e., not a title)? If so, are there other examples? I understand that this is a movie title and titles aren't subject to the same rules as ordinary sentences. I'm just wondering if this usage is fine in a sentence.
