Dead Ringers Movie Trailer

Elliot locks Beverly into the clinic and tries to clean him up, taking pills himself to "synchronize". When Claire returns, Beverly leaves the clinic to be with her. When he returns to sobriety, he is concerned about his brother, and goes back to the clinic. There he finds the clinic in ruins and Elliot despondent and intoxicated. Their positions are reversed as Beverly cares for Elliot. Drugged and despairing, they celebrate their mock birthday and Elliot volunteers to be killed, "to separate the Siamese twins". Beverly disembowels Elliot on an examination couch.
Beverly pulls himself together, leaves the clinic and calls Claire on a payphone. When she asks, "Who is this?", Beverly leaves the payphone, walks back into the clinic and dies in Elliot's dead arms.
