Austin Powers 4 is an upcoming sequel and the fourth installment in the Austin Powers franchise.
It used to be rumored to be called Austin Powers in Thunderballs or Austin Powers: License to Shag and there was also said to be a Dr. Evil spin-off, but it never happened either. Verne Troyer who portrayed Mini-Me had said he had no idea if they are making it.
Later, he stated in May 2017 that in the film, Mini-Me would reveal his ability to speak. However, plans for this failed as Troyer died of alcohol poisoning on April 21, 2018.
Mike Myers had hinted at the possibility of producing a sequel.
