Yeah build the rivarly and tension up between the 2 men. Can have Jack The Ripper be the bad guy in the second film.
Jack the Ripper has been done too many times. I'd like to see one of two (or both) types of villains in the sequel:
1. A totally original villain.
2. The second most dangerous man in London, and Moriarty's top henchman, Colonel Sebastian Moran.
Well what about the Elephant Man?
You're not the same guy from the last thread that kept insisting the Elephant Man WAS Jack the Ripper, are you?
Oh, I know, but the excuse for having her in the movie was that she was working for Moriarty and he wanted Blackwood's device. If she doesn't work for Moriarty in SH2 why would she even be in the movie? She'd probably be in jail or would head back to New Jersey. There needs to be some reason for her to appear in SH2, and all I can think of is that she goes back to work for Moriarty in an effort to double-cross him or Holmes asks for her assistance because she knows Moriarty and his methods.
If Irene Adler is no longer working for Moriarty, I can think of several ways the writers could shoe-horn her back into the story. The crappy reasons we might see her again are literally endless.
1. Adler sticks around to help Holmes take down Moriarty because she knows his methods and how dangerous he is.
2. One of Adler's London based schemes just so happens to overlap one of Holmes cases and the pair meet by accident.
3. Moriarty tries to kill her because she knows too much, and Holmes comes to the rescue.
4. Alder remains in London, and Holmes watches her throughout half the movie because he A. doesn't want her hurt, B. wants to make sure she's not committing any crimes, C. is a tad in love with her.
5. When Watson is with Mary, she could fill in as Holmes' partner.
6. Adler just so happens to know something, or someone, that can help Holmes solve a case (think John Turturro's character in Transformers 2)
7. Knowing she would quit and help Holmes, Moriarty had been feeding her false information, and her whole purpose for being in the movie will be to give that false information to Holmes and accidentally lure him into some sort of trap.
8. Adler is put in jail for a crime Moriarty or the current villain is responsible for (Maybe Moriarty makes it so she takes the fall to get her back for double-crossing him?), and the whole movie deals with Holmes trying to prove her innocence and put the real criminal behind bars.
9. Adler escapes from jail or police custody, and Holmes is called to track her down and capture her.
#8 is the only one I'd even remotely like to see. But, If writers can find ways to stick Arwen in all three LotR movies, I'm sure they can find ways to stick Irene Adler into all the Sherlock Holmes movies.
