Extreme non-verbal acting (Body language) infused in over-the-top delivery of dialogue, is the backbone of commercial comedy . This acting style is mainly utilized in Nollywood films and is fast becoming the norm.
This style is easily adopted in West Africa because some tribes are actually very expressive. The growing acceptance of Nollywood movies, is an indication that this is the new trend.
It must be noted however that acting style is dependent on what the Director wants to potray. My point here is for commercial purposes there is a trend towards "Over-acting"
