Leonardo DiCaprio has signed to play twin brothers (he did so previously in Man in the Iron Mask) in Johnny Eck, Daily Variety reported today (Tuesday).

The real Eck, who was born John Eckhardt in 1911 and died in 1991, lived much of his life as a circus sideshow freak. (He was born without lower extremities.) His twin brother, Robert, who died in 1995, was physically normal. The film is expected to focus on Eck's exploitation by magician John McAslan.
