Langenkamp was led into a "chamber of horrors." The bathtub scene, in particular, was one of the hardest for Langenkamp to film.
Craven modified the tub so that a man in a scuba suit was able to lay beneath Langenkamp and make it appear as though Krueger's hand was emerging from between Nancy's legs. "So Jim [Doyle, VFX engineer] is blindly plunging that thing between my legs," Langenkamp recalled. "One time it's too far to the right, next time it's too far to the left, then it's way too fast—and Wes just patiently waited until he got the take that he wanted."
