J. L. Moreno gave some directing tips quoted here from Psychodrama, Vol I, page 257 :
“The director should work with the minimum expenditure of emotional energy. Once a production has begun he should leave its development to the subject.”
[This indicates we should follow, rather then lead, the protagonist.]
“When and where guidance is required he should leave this to the auxiliary ego co-acting in the scenes.”
[Guidance is the operative word. The director can relax if the auxiliary egos are performing well, however, the director must direct when necessary.]
And I thought directing required imposing tight control, er... structure...and had to be tense with really hard work.
