Loopers

Bruce Willis, Joseph Gordon-Levitt, and Emily Blunt in a movie about time-traveling hitman (called Loopers) that carry out contracts to kill people to include themselves eventually.  In this case Bruce and Joseph Gordon play the same character - a looper named Joe.  Bruce is the older Joe and Joseph Gordon is the younger Joe. 

Bruce wants to change the future, traveling back in time to make it so.  Specifically, he intends to kill the man that killed his wife.  Emily Blunt is the mother of the man that Bruce is after.  Joseph Gordon is caught in the middle - maintain the status quo and carry out his plans for the future or team with Bruce.

Good movie... would hold as a safe first date movie but would see it later on in the relationship.  Main reason is the story line does not fit a first date movie, else it still is a good movie.
