Acting classes are considered by many directors to be valid experience and they can make a difference in your modeling portfolio. Most of us are not born actors, so acting classes may be necissary to do the job the way a client wants it done if you have a speaking part
So while modeling classes may be a waste of your time and money, some acting classes may be necissary if you choose to pursue this type of modeling. Many petite and average modles have an easire time in this industry becuse most of the time
size is not a deciding factor. The ability to do the job well is more important. The industry is still competative, but if you have experience modeling in non speaking background parts it makes breaking into this sector much easier.
