X-Men kick started the modern age of comic book movies in 2000, but 1998's Blade is regarded as the spark that ignited it all. The movie didn't make a big splash at the box office, but it wasn't a flop, either. While it wasn’t loved by the critics, it was a cool comic book-based action flick.
Kevin Feige also thinks Blade was a cool movie. During an interview with JoBlo, the Marvel boss, who recently said that the MCU might produce some R-rated flicks in the future, noted that Blade should get the credit for its role in the success enjoyed by today's comic book movies:
My tenure at Marvel started 17 years ago, and there were two things that sort of launched the modern era. One was X-Men, which was the first thing that people said, “Oh, there’s life here.” But a few years before that, there was Blade. A character nobody had heard of at all, had only appeared in a few issues of Tomb of Dracula or something, turned into a big franchise.
Feige added that Blade was the perfect example of an unknown comic book character who was nonetheless able to support a profitable franchise:
That was always a great lesson for me, where you go, “It doesn’t matter how well known the character is, it matters how cool the movie is.” Which, many years later, would be the reason we do Guardians of the Galaxy, Doctor Strange.
So are there actual plans for a new Blade movie? There was some talk a couple of years ago, and Wesley Snipes said that he was ready to reprise the role. There were even negotiations (which thankfully failed) for a crossover with the Underworld franchise (Marvel didn't agree, and fans took that to mean that a Blade film would be made).
Unfortunately, it appears that there aren't any such plans, even though the rights reverted to Marvel in 2013 (the same year MCU characters Punisher and Ghost Rider returned home). Feige didn’t rule it out:
We think it would be cool. Someday. I think Blade is a legacy character now, and I think it would be fun to do something with him one day.
