Sweeney Todd versus Jack Colton

This is an odd post after I just wrote one saying I'm not a huge fan of how big a time suck video games can be. But anyway...

I actually had this idea while Sweeney Todd was dancing about with a pair of knives. Wouldn't it be cool if you could take some of the more interesting characters from movies and make a video game starring all of them? So you'd have Todd, Jack Colton from Romancing the Stone (just watched that one this morning), Snake Plisken from Escape from New York, Kyle Reese from the Terminator, Private Vasquez from Aliens, etc. You get the idea. Let 'em all fight each other and you get to play as whoever you want. It would be like one of those epic comic book games where you can play as 800 different heroes and villians. This would be wicked fun.
