A lot of times I think things like this are from dance training that looks good on film...
I did read that Jennifer Garner studied dance as a child. Good for her. Dance requires rythm, timing, balance, endourance, and strength to name a few. These dance attributes are also very common in MA, no?
... but might not be an effective technique.
Agreed. She was doing 'Movie-Fu'. But she did have to learn to do some of the things filmed on her show. She did also have a stunt and MA double for some of the more technical scenes. So then, what makes an 'effective technique'? Flow/fluidity? Power? Speed? Actual contact?
Jennifer Garner has my vote for this Movie Star MA list even though she was a dancer first
