I'm not type to wax nostalgic over the loss of celebrities but Wilder was a unique cat. I vividly remember watching Willy Wonka & the Chocolate Factory as a child; I was as memorized as I was terrified. This character, this man, was weird and I couldn't take my eyes off of him.
It's scary to take the reigns. It's easy to make choices when you have reliable support. It's easy to make decisions when you have someone to validate them. In these situations: observe, absorb, learn.
