Robert Downey Jr, who plays Sherlock Holmes in the upcoming Guy Ritchie film, has revealed that the action movie could be the first in a franchise.
"I feel like there's going to be a Sherlock Holmes 2," Downey told MTV.
Downey Jr went on to say that Holmes's addiction to opium, explored in the original novels, will not play a prominent part, keeping the film suitable for family viewing.
The Iron Man star explained: "I actually petitioned the court and said, 'This is a PG-13 movie. Let's just refer to these peripherally.' So at one point, Watson says, 'What are you doing, that's for eye surgery!'"
