Deathtrap (1982)
Lumet's 1982 stage-play adaptation. The script doubles back on itself three times.
Actor: Christopher Reeve
Christopher Reeve played Superman across four films and gave the character a distinction between the two identities built entirely on posture and voice. He was paralysed in a riding accident in 1995 and spent his remaining years as a spinal research advocate, testifying before Congress and founding a substantial foundation.
