When Yoda appeared on screen I remember thinking, there's that funny looking little troll guy that I saw a picture of in the program...And I was convinced that he was trying to help Luke find Yoda, picturing someone named Yoda as a Jedi like Obi-Wan but the name threw me.
Yoda was performed so well, I totally was lost in thinking that this was a real creature...And in a lot of ways I still feel that way when I watch it.
A brilliant creation..
