Between Reservoir Dogs and Pulp Fiction, Quentin Tarantino approached Laurence Fishburne to see if he'd like to star in a Marvel movie. This was when the words "Marvel movie" would have filled me with dread.
Here's Tarantino, speaking to MTV:
After Reservoir Dogs, I had considered doing a Luke Cage, Hero for Hire movie. Ed Pressman owned the rights at that time, and we talked about it. I talked to Larry Fish about being Luke Cage, and he really liked that idea. Then I ended up writing Pulp Fiction.All talk, no pen to paper. I'm sure had Tarantino even written one page he'd have told us about it. Still, we got Pulp Fiction and that's nothing to sniff it.
The roots of Luke Cage were in blaxploitation, and Tarantino has already drawn from that well. On the one hand, he has shown that he "gets it," on the other hand, he may feel that he's done with that genre - if it is a genre, it's arguable - and doesn't need to visit it again.
Here's a look at Fishburne in Deep Cover, the film he did make in 1992. This will give you some idea of what his Luke Cage would have looked like.
