The Dismissal (miniseries)

The Dismissal is an Australian television miniseries, first screened in 1983, that dramatised the events of the 1975 Australian constitutional crisis.

In the 1970s there were several attempts to make a film based on the same story called King Hit written by Erwin Rado and Bruce Grant. Phillip Noyce and Paul Cox were both attached as directors for a time.
