Jeffrey says his proudest accomplishment is having built a doll house for his daughter for her 12th birthday.
There is a ritual on the set of Jeffreys's show Mercy Peak that when a person's temper gets the better of him he is given a handbag to throw on the floor and kick about. Then they have to carry it with them for the next ten minutes as penance and warning to others. Jeffrey was given the handbag more than once.

Jeffrey: I like the physical side of acting, but most modern dramas are set in an office.
Jeffrey: I started acting on a whim and found I loved it.
Jeffrey: (when asked to compare working on "Hercules" and "Dark Knight") They're quite similar. Hercules is more lavish and better paid and shot on 35mm as opposed to the 16mm on which Dark Knight is shot. Technically this makes quite a big difference but in terms of the work an actor does there's virtually no difference.
Jeffrey: (on his role of Mordour in "Dark Knight") I was attracted by the prospect of having a lot of acting to do and I rather enjoy acting.
Jeffrey: (on making a TV show) There's a lot of waiting around, a lot of inertia. Then boof. It doesn't matter what kind of scene you're doing, you have to be ready to do it at a few seconds' notice. That's the craft.
