Carter, Duchovny and Anderson celebrated the 20th anniversary of the series at a July 18, 2013 panel at the San Diego Comic-Con hosted by "TV Guide". During the discussion, Anderson discussed Scully's influence on female fans, relating that a number of women have informed her that they entered into careers in physics because of the character. Anderson also indicated that she was not in favor of an "X-Files" miniseries, and Duchovny ruled out working with her on an unrelated project, but both expressed willingness to do a third feature film. Carter was more reserved at the idea, stating, "You need a reason to get excited about going on and doing it again." The series attained a degree of historical importance, as well. On July 16, 2008, Carter and Spotnitz donated several props from the series and new film to the Smithsonian's National Museum of American History. Some of the items included the original pilot script and the "I Want to Believe" poster from Mulder's office.
