In 2014, Denzel Washington took over Edward Woodward’s ’80s TV role as the retired spy turned revenge specialist Robert McCall for a big-screen version of “The Equalizer.” The film earned $192 million worldwide. Now he’s back in “The Equalizer 2,” which has just released its first trailer, and — stop us if you’ve heard this one before — this time, it’s personal.

After his friend and fellow former operative (Melissa Leo) is murdered by C.I.A.-trained assassins, McCall vows, “I’m going to kill each and every one of them, and the only disappointment is that I only get to do it once.” Cut to scenes of guns blazing and bones snapping.
