The cast of "Star Wars 7" may not be open to discussing the plot of the movie yet. Some of the cast members, the latest being Harrison Ford, have finished filming their scenes in the movie. The director has reportedly put up posters around the sets warning the crew not to disclose secrets of the movie.

Production of "Star Wars 7" had to take a brief hiatus in August following Harrison Ford's injury on the set. According to a report by DailyMail, the 72-year-old actor has now finished filming all his scenes and was reportedly seen walking about. He had to use a wheelchair and a leg brace right after his leg injury.

The director of the film, J.J. Abrams, has been trying to stop the leaks that are taking place from the movie sets. One of the posters reportedly put up around the sets shows a Darth Vader's gloved hand on an Imperial officer with the words "Loose lips bring down starships." This, however, has not stopped the leaks from happening.

"Star Wars 7" is one of the most highly anticipated movies of 2015. Production is still ongoing for the movie. It is slated to be released on Dec. 18, 2015 in Australia, Canada, the UK, New Zealand and the U.S. There have been multiple leaks from the movie that range from details of the plot to concept arts.

One leaked concept art is of Han Solo's costumes showing two designs, one suitable for a cold planet like Hoth while the other is more suitable for a desert planet like Tatooine. The role of Han Solo is played by Harrison Ford in the movies. Click here to look at the leaked images.

Harrison Ford will be joined by two of the cast members from the original trilogy as well as some new ones. Mark Hamill and Carrie Fisher will be reprising their roles as Luke Skywalker and Leia, respectively, in "Star Wars 7." Some of the other cast members in the movie include Adam Driver, Gwendoline Christie, Andy Serkis, Domhnall Gleeson, Lupita Nyong'o, Peter Mayhew, Max Von Sydow, Oscar Isaac, Daisy Ridley and John Boyega.
