Head Modeling in games

[gogo76]

Sorry for making another post, but I have another question regarding human head modeling.

I'm looking into buying the Modeling the Human Head DVD. Does this DVD give you a fast and efficient workflow for head modeling, that can easily be integrated into the development of a video game?

Is box modeling, the method used in this DVD, a good way of making a polygonal head?

Can the head created in the DVD be easily given to an animator for him to rig it and animate it?

Thanks a lot for your help in advance.
