Star Wars actress Carrie Fisher attended the Calgary Comic and Entertainment Expo recently, where she dropped a pretty big hint about her role in the upcoming Star Wars: Episode VII movie.

56-year-old Fisher joked, ā€œIā€™m glad they are doing a new movie because they are sending a trainer to my house so I can get in really good shape," reports the Calgary Herald. "So I'm really eating a lot of sugar in advance, as you can see. By the time I really get down to it I will have eaten everything."

Before this, Fisher and her costars, Harrison Ford, 70, and Mark Hamill, 61, had been secretive about their possible involvement in the new film, but creator George Lucas let it slip earlier this year that they would in fact reprise their roles.

"We had already signed Mark and Carrie and Harrison -- or we were pretty much in the final stages of negotiation. So I called them to say, 'Look, this is what's going on,'" Us Weekly reported.

He continued, "Maybe I'm not supposed to say that. I think they want to announce that with some big whoop-de-do, but we were negotiating with them. ā€¦ I won't say whether the negotiations were successful or not."
