Code names for in-production movies: 2001: A Space Odyssey was referred to as “How the Solar System Was Won” during production, while Alien was known as “Star Beast”.

Wikipedia’s naming convention guidelines for movies titles, with directions on when – and when not – to capitalise the various words that make up the title. Useful across the board, not just at Wikipedia.

Each word in a film title takes an initial capital, except for articles (“a”, “an”, “the”), the word “to” as part of an infinitive, prepositions, and coordinating conjunctions shorter than five letters (e.g., “on”, “from”, “and”, “with”, “about”), unless they begin or end a title or subtitle. For example: Angels and Virgins, End of the Spear, Failure to Launch, I Am a Fugitive from a Chain Gang.
