Mike Myers has started writing a fourth "Austin Powers" which will be a homage to his father reports Deadline Hollywood Daily.

This fourth installment of the super spy spoof movie series will focus on Austin's arch-villain Dr. Evil and his relationship with his son Scott Evil (Seth Green).

"It's very personal with a father and son theme loosely based on his own life," an insider tells the site.

Myers is apparently co-penning his idea with Mike McCullers who previously worked with Myers on the two 'Powers' sequels.
