AUSTIN Powers may be coming back for an encore to “Goldmember,” despite earlier promises by Mike Myers that this would be the last mission for the shagadelic Brit spy.

“We thought this one would be the third and final chapter, but Mike just keeps coming up with hilarious new characters and situations, so a fourth one seems more likely now,” directorJay Roach told The Hollywood Reporter.

“Goldmember” racked up an estimated $73 million during its first three days – $76.6 million including Thursday-night previews – the biggest July opening ever and the fifth-biggest three-day opening of all time.
