Here is a partial list of some actors that are also great fine artists.
Most of these artists work either in the canvas and paint medium or in spoken word. Some have been doing it along time others not so long. I think these are all worth a look at!
Some of these guys I have linked to, others you will have to google.
I found this fascinating and hope you do as well.
