When one watches the David Regal DVDs, much more than a few effects are learned. The title of the series tells you just what you'll get - Power, Premise and Presentation.
Each of the DVDs focus on one of these elements, and David shares his insight on them - this alone is almost worth the cost of the series. This is not to diminish the effects though.
Everything on this series is audience tested and very doable, some require gaffs, but they're usually readily availible, if not already in your close-up case.
The only problem is that his performances are so hysterical, and incredible you feel as though you're doing them a great injustice performing them yourself. If you don't have this already, but it now.
