Austin Powers 4?

According to Moviehole that there’s a rumor has been floating around about a fourth Austin Powers film.

Recent rumours suggesting a fourth “Austin Powers” movie being in the works were quickly
debunked by, well, someone who seems to think they know it’s not. Today
however, Jay Roach, director of the three “Powers” pics, told MTV
that the new movie is still a possibility.

The first one was funny, the second was even funnier, the third had a few chuckles but it had the exact same damn jokes from the previous, but reversed.
Making another would be lifeless, unless they come up with something new.
