Here's the problem I had with this initial rumor. The 'source' of the rumor about Harrison Ford being out for 6 months came from The Sun, a freaking tabloid who's sole purpose to post sensationalized article. From there, everyone started adding their own thoughts to it. It's the nature of rumors, they can get out of hand.

I'm sure there was a meeting about Ford's injury. That's likely to happen regardless of how big an injury it was. Anyway, I can't see them delaying the film. Disney is pretty set in their release dates, and I don't see them changing it. If they did, I would expect them to come out and say something fairly quickly.

I posted on FB earlier about how films are made and how this is not a big deal. Most films are shot in 6-12 weeks give or take. The rest of the time is used for CGI work, editing, and other tweaks. Any film of size will have reshoots scheduled as since films are shot out of sequence when it is assembled new stuff is often needed. It can be as simple as saying we need a better transition here, perhaps we need to add a scene for this character(s) or something is not working so they decide to change it. They will shoot around him as best they can and if it is say 2-3 months from now when Ford can return, they can film what is needed with him and the needed cast and go on as planned. I am sure all key members of the cast have a provision in their contracts that reshoots will be needed and as such they need to be available. I am also sure that the moment Ford was injured they had a timeline and a backup in place to ensure that all needed cast and crew would be able to be there. Not to be mean but lets look at the facts. Mark, Carrie, and the original cast do not have much aside from the new films and some voice work that will keep them away and the new cast knows how key this film is to their future. If Ford cannot film on this movie he cannot film others so they will wait for him. as they have to.
