What's the movie name of the film where a former gangster gets recognized after he stops an armed robbery at his sandwich shop and his former gangster partners come back to try and kill him and his family

http://www.imdb.com/title/tt0399146/

Is this your movie?

Edit: I'm not sure why that didn't come up as a link, but the title is
A History of Violence with Viggo Mortensen and Maria Bello

That is it. I've been trying to figure it out for a few days. Thank you for your help.

No problem, it is a really good movie.
