Shrek and Puss in Boots are Being Re-Booted
The "Shrek" franchise is being rebooted, along with its spin-off "Puss in Boots". The producer behind the "Despicable Me" franchise is overseeing both. He's developing new storylines, but he wants to KEEP the voice cast from the original movies, including Mike Myers, Eddie Murphy, and Antonio Banderas. Nothing is official yet.
Even with the same cast, it would be a "reboot." He says, quote, "The challenge for us has been to find something that really does feel like it's not simply yet another film in a series of sequels." It's unclear what he means... but it suggests that they're scrapping any previous scripts or plans for "Shrek" and "Puss in Boots" sequels.
There were four "Shrek" movies, which were released between 2001 and 2010. There's been talk of a fifth for years, but it never happened. The "Puss in Boots" movie came out in 2011. A planned sequel has been in limbo since 2015.
