Actor Arnold Schwarzenegger surprised his fans when he revealed that his film 'Twins' was his most profitable film of his career, despite being known for his superhit franchise 'Terminator', reported Variety.

During an interview on the 'Watch What Happens Live' talk show, as quoted by Variety, Arnold said that 'Twins' delivered him 40 million USD. It was a comedy-drama that starred Arnold and Danny DeVito in the lead roles, marking their first collaboration on the big screen. The movie was released in 1988.

"Well, number one was 'Twins' because we got no money for the salary, but ownership with a piece of the back end. It was fantastic. We went all the way to the bank with that," said Arnold as quoted by Variety.
