Season four of “The Crown” has started filming with additions like Gillian Anderson (Margaret Thatcher) and Emma Corrin (Princess Diana).

But there is one addition that fans are even more excited for- Prince William.

The cast was spotted filming in Spain which played the spot of Prince Charles and Princess Diana’s 1983 royal tour of Australia.

One of the highlights of that tour was a 9-month-old Prince William who joined his parents.

Photos taken of the stars on set show a baby Prince William being carried onto the plane.

Season four will take place roughly between 1979 to 1990, so there is a good chance that Prince Harry (who was born in 1984) will also make his debut. ET Canada has reached out to Netflix to confirm if everyone’s favourite redhead will be in the fourth season.
