It's an industry "secret". You don't want to start your pr campaign too early because you might not have the money to keep it up, leading to audiences internalising it and assuming everyone forgot about it because it was bland/shit. You also don't want to risk explaining why cast lists might have changed (as frequently happens between the start and end of filming).
