The mother, Mary Ann Benedict, was told that Julius died at birth, and not told about Vincent at all. To the surprise of the scientists, the embryo split and the twins were born. Julius and Vincent Benedict are twin brothers, the result of a secret experiment carried out at a genetics laboratory to combine the DNA of six fathers to produce the perfect child.
Instead of taking their usual salaries for the film, Schwarzenegger, DeVito and Reitman agreed with the studio to take collectively 40% of the film's box office and rental returns this resulted in them receiving the biggest paychecks of their film careers. The film was a commercial success, grossing $216 million worldwide. The core of the film is the contrast between the streetwise Vincent (DeVito) and the intelligent but naive Julius (Schwarzenegger).
The film is about unlikely fraternal twin brothers ( Arnold Schwarzenegger and Danny DeVito) who were separated at birth. Twins (rendered in its title sequence logo as TWiiNS) is a 1988 American buddy comedy film produced and directed by Ivan Reitman.
