Johnny Duncan(1923-2016)

Was the second actor to play the Batman's sidekick, Robin, the Boy Wonder, AKA: Dick Grayson.

So I had this fight with Kirk Douglas [as Spartacus], a sword fight, and he cuts my head off. And when he cuts my head off, this [fake] blood and stuff squirts out like the veins in my neck. And, my God, they had to cut it, it was so gruesome. It squirted all over Douglas, all over the other actors around and everything, and today it would have been great ... But in those days, they said, "Oh, my gosh. We can't let that be in the film."
