Step 1 : Introduction to the question "9. Which actor played Arnold Schwarzenegger's twin brother in the 1988 movie 'Twins'?"
...1. Morgan Freeman 2. Danny De Vito 3. Sylvester Stallone 4. Pierce Brosnan Schwarzenegger was Julius Benedict and Danny De Vito was Vincent, his long lost twin brother. The rather odd twins were the result of an experiment; Julius was the perfect result and Vincent an accident. Julius was clever and Vincent was a small-time crook, but they were delighted to find each other. Kelly Preston also stared in this amusing story of the newly-reunited brothers' search for their mother.
