$2M budget in 1972-73
I am always amazed at how much they did with a relatively small budget. The futuristic buildings and other complicated gizmos. The giant fruits and vegetables looked pretty hard to make. The flying, motorized space suit they ride across the lake in. I looked closely but I couldn't see any wires when Miles bounced around. And this was the way they had to do it back then with no CGI.
