"On the bog planet set in Empire Strikes Back we used a creeping vine that is called Old Man's Beard. When we were done with the bog planet we took all that creeper down and left it up on the backlot of the studio, thinking we might use it again. Well, when we built the Raiders' temple set in the studio, we used a lot of that Old Man's Beard again."
-Associate Producer Robert Watts from the Raider's Movie Special Magazine 1981
