During the week of October 8, @Castlegrip, Christopher Brow gave Castle fans a new behind the scenes look at the show and life as a dolly grip while filming “After Hours.”

Describing what he does on set, he wrote, “I work around the camera but I’m not part of the camera crew. I’m a grip but support the camera. I’m a Dolly Grip.”

One day on the set, Christopher posted a picture of the set up for a car scene.  He tweeted that these type of scenes do not require dollys because of the lack of moving in the scene.

After posting a picture of the crew wetting down the pavement, Christopher was asked why they seem to always do so.  He explained that the shine from the wet pavement reflects the light and also ads contrast to the scene.  When it rains on set the crew is under cover.  He also said graffiti in scenes is put there by the set painters.  The tubes on the stages, seen in some pictures, are air conditioning tubes.

He said they film directly on the stage floor or lay “dance floor” during scenes.  If the ground is not level, they lay track.

He also included information about the dolly he uses.  It is a J.L. Fisher model ten dolly.  It is provided by production but he has always used it.

Finally, Christopher told fans:

@kc_autumn it’s my way of trying to give back for all you do. Watching castle keeps us employed.Thank you
