John Noble, Anna Torv, Lance Reddick, Joshua Jackson, Jasika Nicole and executive producer J.H Wyman were at the San Diego fan convention to celebrate the upcoming finale and were all optimistic that Fringe would live on in some form after the finale in 2013.
"The film is very possible down the line," said Noble, which was greeted with cheers from fans in the crowd.
"The show will live on in some form or another," added Jackson. He later added that the show has a comic book writer and artist "at the table" and suggested that fan fiction would also keep the show alive.
Exec Wyman also confirmed to fans that the new season would "pick up exactly where we left off" in season four and revealed that he had decided on the show's ending "two or three months ago".
Fringe's final 13-episode season will start on September 28 on Fox in the US. It will air in the UK on Sky1.
