While talking about Jay and Silent Bob Reboot during a Fatman on Batman Q&A (via Comicbook.com), Smith compared the project to Gus van Sant’s Psycho remake, and while Jay and Silent Bob Reboot isn’t a total shot-for-shot, word-for-word redo like the 1998 Psycho movie was, Smith acknowledged that he looked to the Jay and Silent Bob Strike Back script to build the new movie’s script.
When Jay and Silent Bob Strike came out, X-Men had only come out the year before, meaning that superhero movies hadn’t yet become a Hollywood mainstay.
So while Jay and Silent Bob Reboot’s main plot is derivative (Smith mentioned that there will even be a new group of girls riding around in a van), rest assured, there will be plenty of new elements.
In fact, sequels, remakes and reboots have become more widespread among other cinematic genres.
