If there's one thing Spider-Man 3 taught us, other than the fact that we never want to see Tobey Maguire dance ever again, it's that too many characters sink a superhero movie.
It was a problem faced by this summer's Spidey sequel and it looks like it'll plague Zack Snyder's much-anticipated and much-feared Batman Vs Superman: Dawn of Justice, which hits in 2016.
The latest rumour doing the rounds is that Emily Blunt, currently showcasing her impressive action credentials in the excellent Edge of Tomorrow, will be joining the film as Catwoman. Because a film which already features Batman, Superman, Lois Lane, Lex Luthor and Wonder Woman really needs another major character.
Reports have surfaced on a number of sites that suggest she is is very close to signing up but no confirmed word has been released just yet. It's not the first time she's been linked with a superhero film having been touted for roles in Captain America, The Avengers and as Catwoman in The Dark Knight Rises.
There's no doubt that an actress of her quality would make for a fine Catwoman but do we really need to see that character reinvented so soon?
She would join Henry Cavill, Ben Affleck, Amy Adams, Jesse Eisenberg, Jeremy Irons and Gal Gadot in the film.
