It's one of the most debated theories in sci-fi - is Harrison Ford's character in Blade Runner human or an artificially created replicant?
The answer was left as a mystery in the theatrical release of Ridley Scott's 1982 film - with even Scott and Ford arguing about it - and with a sequel due to be released in October, fans are hoping the issue will finally be resolved.
Ford and fellow cast members including Ryan Gosling introduced a second trailer and new clips from the movie at Comic-Con on Saturday, which connect the sequel to the original film.
Moderator Chris Hardwicke couldn't help but ask Ford if Blade Runner 2049 would address the lingering questions about Deckard's identity - human or replicant?
After a long pause, the star responded: "It doesn't matter what I think."
