Bad reaction

As well as directing Spaceballs, Mel Brooks, played both the bumbling President Skroob and Yogurt - golden-faced, merch-loving spoof of Yoda.

To sell the joke, Brooks wore gold makeup instead of green, but it didn’t go smoothly.

It gave him a severe allergic reaction that had to be treated nonstop with Benadryl, despite the crew swearing it was non-toxic.
