R2-D2 was so small during the making of Star Wars that a little person (Kenny Baker) had to crawl inside to control R2-D2’s every action. While there is absolutely nothing wrong with the original R2-D2 it’s not made for normal sized folks, but now that has changed.
A fan of the Star Wars series created his very own, larger, R2-D2 figure which he is able to crawl inside of and then operate just like the original.
The video below shows the fans creation with working lights and sounds.
I particularly like the “What’s Daddy doing?” question for his kids.
