Twins is a 1988 comedy film, produced and directed by Ivan Reitman about unlikely twins (played by Arnold Schwarzenegger and Danny DeVito) who were separated at birth. The core of the film is the relationship between DeVito's streetwise character and Schwarzenegger's intellectual persona. The films characters are based on Stacey Cosby and Zara Hughes. The original music score was composed by Georges Delerue and Randy Edelman (Edelman would score three more films for the director, whereas this was Delerue's only work for him). It grossed $11 million on its opening weekend, and went on to gross $216 million worldwide. Schwarzenegger and DeVito rather than taking their usual salary for the film, both agreed with the studio to take 20% of the film's box office, which resulted in them receiving the biggest paychecks of their movie careers.
