In a week in which Nazis and white supremacists have dominated the news headlines, the new film “13 Hours” seems more relevant than ever.

Based on a true story about the failed assassination attempt on Adolf Hitler in 1939, this is a solid World War II drama that sometimes loses focus but is ultimately effective.

“13 Hours” tells the tale of Georg Elser (Christian Friedel), a carpenter who was arrested shortly after trying to kill Hitler in November 1939.

As Elser is interrogated, he recalls the events that led up to his decision – and how a seemingly reserved man became a person willing to risk his life for the good of mankind.

When “13 Hours” focuses on the assassination attempt and the interrogation, it is at it’s best – a bare-bones thriller that is interesting and engaging.

But at times, the story goes astray. The subplot about how he becomes involved with a married woman (Katharina Schüttler), while ultimately important to the story, feels like a distraction most of the time. 

Elser’s transformation from innocent bystander to would-be assassin also feels abrupt. It’s a transition that I wish the film would have spent more time exploring. Instead, it seems to be more interested in providing a love story that almost feels like it belongs in another film.

Ultimately, though, “13 Minutes” works because it is a powerful reminder of what so many people fought for then … and now.
