Katana Vs. Silver Samurai

The Silver Samurai always struck me as an imposing figure, I really liked the design of his armor.  It was cool to see him in live action in The Wolverine, even if it was a somewhat altered version.  Heck, he even retained his coolness when he faced off against John Belushi when Spider-Man met the original cast of Saturday Night Live in that classic issue of Marvel Team-Up.

I was unsure whether Scarlett Johanssen's Black Widow would have the clout to carry her own film, but I have to admit that I have liked the character more with each appearance that she has made.  I think a Black Widow-centric movie could work pretty well, especially if she could have some cool supporting heroes along for the ride.  Who knows if Johanssen will be available though, as it is rumored that she is close to signing on as the lead in  the Ghost in the Shell adaptation.
