"Star Was Episode 7" will reportedly begin filming in April, but no word as to which original cast members are likely to return.  However, Disneyland Imagineers are aware of the new characters and storyline for the upcoming film, according to Micechat.com.

Check out what Micechat.com sources revealed below:

"The Imagineers assigned to the Star Wars Tomorrowland project have now been debriefed on the characters and plotlines coming for Star Wars Episode VII that opens in theaters in about two years.

"The original plan for Disneyland's Tomorrowland relied heavily on characters and plot points from the first three Star Wars films, with attractions like a Millenium Falcon walk-thru on the old PeopleMover platform, a wild Tatooine cantina replacing Tomorrowland Terrace, and a speeder bike ride through an Ewok village where Autopia currently sits.

"Those key attractions are all still part of phase two, but they are being layered or tweaked to include references from Episode VII that will be released in theaters at least 18 months before any of those attractions open."

A revamped Tomorrowland will not likely be unveiled until sometime in 2017.  "Star Wars Episode 7" is set to hit theaters on Dec. 18, 2015.
