11 Amazing Times Actors Played Other Actors Playing Characters 

The Players: Steffan Rhodri playing Rupert Grint playing Ron playing Reg

Mode Of Body Swap: Polyjuice Potion

Ron is a dope. He has little to no business going Horcruxing with Harry and Hermione. And before you get your Hufflepuff robes in a bunch, remember that he literally abandons them mid-adventure because it was hard and he missed meat pies and the warmth of a freshly-knit “R” sweater.

But narratively, he’s there to keep things relatively light by stumbling into awkward situations. Like the one he gets himself into when he Polyjuices into the form of Reg, a Ministry of Magic maintenance worker.

While Harry and Hermione go off to do more sneaky, clandestine stuff around the Ministry, Reg/Ron is called away on a side mission to make it stop raining in some guy’s office. Steffan Rhodri does a lot with little screen time, before transforming back into Rupert Grint right in the middle of a passionate kiss with Reg’s wife.
