Did You Know?


Two of the characters from 'Men In Black'; Agent K & Agent J, are mentioned by Castle in this episode. In the third 'Men In Black' movie, the actor who plays the young Agent K (Josh Brolin) is the real life son of James Brolin who plays Jackson Hunt (Castle's father) in this show. See more »


When Stack is answering his phone, you can see the iPhone menu. When you have a phone call on an iPhone, the screen turns off thanks to a sensor next to the speaker so that you don't accidentally hang up by nudging the touch-screen with the side of your face. If there was a real call, the screen would be black. See more »

Another unusual episode
7 May 2013 | by (Arendal, Norway) – See all my reviews

This is an unpredictable episode. With a car exploding in the streets of New York, NYPD has to work on the case with a lack of material and resources because the FBI are taking the case. Why? They don't know. Until later, of course.

Castle has changed. The show, not the character. Most of the latest episodes are not like Castle used to be. Maybe they have gotten a much more Hollywood-ish director that loves clichés? That is what has happened. Maybe the producers think that their fans don't like the old-school Castle, so they have to boost it up with bombs and non-stop excitement?

The last episode was a bit like what I just described. This episode was a little more Castle-ish, but still a bit more Hollywood than usual. A case that the Precinct can't access from the government and work underneath the radar. An overall good episode but a little too more of unrealistic excitement and Hollywood-clichés. 8/10.
