According to this article I found (written in 2010) - individual movie titles can not be copyrighted. However, there can be a trademark granted if there is a certain level of recognition of the title to the specific movie. The author of the article cites "Star Wars" or "Citizen Kane".
Per the linked article, the MPAA has a Title Registration Bureau which also has a standard in place. Participants are notified of conflict; if a raised objection is not settled - the dispute moves to arbitration.
So - to answer your question - for the vast majority of film titles there is no mandatory waiting period. However, producers should not be shocked if there is litigation that arises regardless.
