Its the marketing department's job to make Trek popular enough to be a summer blockbuster at least for the initial phase. After that, good word of mouth will determine whether it has legs.
Everything is unknown at some point, and has to be made popular by the usual means. Iron Man made $300 million dollars despite being a superhero "nobody's ever heard of" (outside of the halls of nerdom). The wholly original Hancock, WALL*E and Kung-Fu Panda made $200M+. Good marketing + worthwhile movie = big bucks.
You need to talk with normal folks more. All the normal folks I know had no idea why anyone would make a movie based on Iron Man. Remember, most people don't visit comic book stores.Like Transformers, Iron Man and Lord of the Rings, people know the name Star Trek
In any case, how do you explain the success of Hancock, WALL*E and Kung-Fu Panda? Nobody's ever heard of them because they didn't exist.
Comic book stuff seems to be regarded as pretty cool by mainstream audience nowadays
Not that I've noticed. The normal folks I know regard comic book movies with slight contempt, but if there's something cool about the movie - like Robert Downey Jr.'s performance - their minds will change quickly and their prejudice will vanish. Their negative opinions about comic book movies are not strongly held - most people just don't care one way or the other. Star Trek has an incredible opportunity because the field is wide open.
Please don't tell me who I need to talk to, and generalize about what and who 'normal people' are. I live in New York City, full of a diverse and multicultural group of normal people. Some like sci-fi/fantasy/comic book stuff, some do not.
If you're calling the majority of people who saw Spiderman, Lord of the Rings, Iron Man etc. 'abnormal' than you have quite alot more living to do. Millions of people saw those films, many of whom are casual film goers. This speaks directly to my point about Trek finally being able to cross this threshold, Star Trek IV did this very well and I'm happy to read people's hunches on this new Trek.
