Washington's character fights with his son in the movie but in real life the actor said that his sons are more physically powerful than him these days.

Washington is currently filming upcoming crime-drama movie "2 Guns" alongside Mark Wahlberg and Paula Patton. The motion picture tells the story of DEA agent and a Naval Intelligence Officer investigating each other because they believe each other is stealing money from the mob.
