This link takes you to Roger Ebert's reviews of Schindler's List and The Chant of Jimmy Blacksmith. As well as links to his Wikipedia page and his IMDB entry, which shows that he has had a long involvement with the film industry and not just as a writer of novels that have been filmed. https://www.rogerebert.com/cast-and-crew/thomas-keneally
In Fred Schepisi's 'Devils Playground', Keneally played Father Marshall and in this clip he gives the boys at the seminary (Werribee Park Mansion) a sermon on hell. https://www.youtube.com/watch?v=i7haqLuIKag
