The only reason I’m aware of this is that this movie was on television late at night not all that long ago. You should take the fact I watched it as an indicator to how bad Australian television is!
Tom, Dick and Harry was released on the 13th of June, 1941. To my complete bafflement it received an Oscar nomination for Paul Jarrico for Best Writing, Original Screenplay. Maybe this is what “funny” was at the time…!!
