Shirley Thompson vs. the Aliens is a 1972 Australian film directed by Jim Sharman and starring Jane Harders and Helmut Bakaitis.
It is the first feature-length film from Sharman, who subsequently directed The Rocky Horror Picture Show (1975).
In 1950s Sydney, Shirley and her gang discover that aliens have attacked Australia but no one believes them.
[3] Sharman subsequently worked again with both Jane Harders and Kate Fitzpatrick when he directed the original 1973 Sydney stage production of The Rocky Horror Show, which starred Harders as Janet, with Fitzpatrick as Magenta.
The film marks the first screen credit for Sharman's longtime collaborator, designer Brian Thomson, who worked with Sharman on many notable theatre and stage musical productions, including the original Sydney stage productions of Jesus Christ Superstar and The Rocky Horror Show, and Sharman's later films The Rocky Horror Picture Show and Shock Treatment.
