Fans have been waiting years for a fourth entry in the “Austin Powers” franchise, but the films’ director is doubtful it will ever happen after the 2018 death of star Verne Troyer.

Roach, who directed “Austin Powers: International Man of Mystery” and its two sequels, sat down with The Independent to discuss the films’ meteoric success.

“We’ve been trying to think up an idea that could earn a fourth film for a long time, but it’s always up to [star/creator] Mike [Myers],” Roach said. “He and I always thought there was more to do with Dr. Evil.”

According to Roach, the biggest hurdle standing in the way of a possible “Austin Powers 4” is the loss of Troyer, who played breakout character Mini-Me in the big-screen trilogy and also appeared in Myers’ 2008 comedy “The Love Guru”.

“To be honest, I don’t know how we’d do it without Verne,” Roach said. “We always had ideas of revealing a whole life that he had that would have taken his character much further. If Mike cracks it and figures it out, we would definitely do some kind of tribute to him. I’m there if he ever wants to do it.”

Myers, 56, teased that a fourth “Austin Powers” movie could be happening when he spoke with ET’s Nancy O’Dell at the 2019 Academy Awards.

“There are,” he replied if talks were underway about another sequel. “But I can neither confirm nor deny the existence or nonexistence of such a program should they exist or not exist.”

When pressed, he added: “It’s likely to be from Dr. Evil’s point of view. But again I can neither confirm nor deny such existence. That’s all I’m going to say.”

Rumours of a sequel emerged when Myers appeared as Dr. Evil in a 2014 “Saturday Night Live” sketch, and then reprised the character twice on “The Tonight Show” last year. Watch:
