Robin Williams played an acting prank on Stellan Skarsgard while filming “Good Will Hunting.”
Producer Harvey Weinstein revealed what happened while paying tribute to the late actor: “Robin says to [director] Gus [Van Sant] and me: ‘Let’s welcome him to America. I’m going to change the script, and Gus, you tell him it’s all about improvisation.’ So here’s this scene about mathematic formulas, and Robin comes out and goes ‘Jack Nicholson’, and then he does Jack Nicholson.
“And then Gus, he’s pointing to Stellan, and he’s in a state of shock like a deer, and then he does Jack, and he does Bob DeNiro doing the scene, and he’s like doing 15 things, and the crew is totally straight-faced while Gus is shooting. And then Stellan starts to ad lib this Swedish gibberish, because he’s so lost in the scene. And then when Gus yells Cut, 180 members of the crew exploded with laughter, and Stellan looked around and goes ‘what happened to me?'”
