After 
yesterday's blog post about Daniel Craig starring in both the Bond films and the upcoming remake of 
The Girl With The Dragon Tattoo, today I saw the poster for the second 
Sherlock Holmes film and I began wondering if maybe there's a shortage of actors out there to star in all these franchise movies.
As well as playing Sherlock Holmes, Robert Downey Jr is also 
Iron Man and will be in next Summer's 
The Avengers movie. And Chris Evans (not 
that one!) is also in 
The Avengers as 
Captain America, but was the 
Human Torch in the 
Fantastic Four movies a few years ago. And before all this, Sir Ian McKellen was both 
Gandalf in 
The Lord Of The Rings trilogy, and 
Magneto over in the 
X-men films.
Surely they must get confused about which character they're meant to be playing...
