On July 6, 2013, Comic-Con International announced the final list of panels about movies for this year's convention, which takes place in San Diego from July 17 to July 21, 2013. Every year, there are "surprise appearances" at Comic-Con, an annual event that attracts more than 100,000 people and sells out months in advance. Most of the stars for the panels have been either announced by Comic-Con or confirmed by the movie studios, but there are some Comic-Con panels in 2013 that have not yet announced which stars are participating because they want to maintain an element of surprise.
So which celebrities are people guessing will most likely be at Comic-Con, even though it hasn't been officially announced yet that these celebrities will be there?
