Lord of the Rings...Absolutely a fantastic franchise in its heyday. Grossed a load of money and won awards. However, I think this franchise its past its prime with the general public. To generate the same excitment for this that HP did, then we'd have to go back in time about 10 years and build it then. Not to mention, Universal is already trying to corner the market with this Franchise. I just don't believe this would be something that would bring people in from all over the world like HP did.
Star Trek..No, not so much. Although a very large and dedicated fanbase, it just doesnt have the same appeal to all ages that the Harry Potter franchise does. Even with the new movie, the image of this product has changed so much over the years that it'd be difficult to build something that could be true to an actual Star Trek fan. Also, I dont believe that your typical Trekkie would like to see Disney's version of this franchise.
007---Not at all. At this point, the Bond series is simply a parody of itself. With all the men that have played Bond over the years, you're just not going to get that same connection to that character that people have to Radcliffe's version of Potter and the WB movies.
Nope, what Disney needs to do is what they've done over the past 80+ years and come up with new things that people feel a connection to. I'm not saying they need to constantly build multi-million dollar attractions at all, but things do need to continue to evolve.
