Correct film,
"Frank Martin" is Marino Gilorami, a superbo Italian film maker, perhaps most famous now for the fantastic ZOMBI HOLOCAUST aka DR BUTCHER MD.
His Brother Romolo Guerrieri was also in films making some ripper Westerns and crime features.
He also had some kids, two of which are Enzo G. Castellari and Ennio Girolami.
Enzo G. Castellari is of course the dude who gave us such treasures as Keoma, 1990 Bronx Warriors, New Barbarians, and MUCH more.. I guiess all you QT fanboys know who made INGLORIOUS BASTARDS?
Ennio Girolami acted in films from Nights of Cabiria to Tenebre.
Enzo's children also acted and made films.
one of which is Andrea Girolami, who not only made some great TV and short films, acted in many AND to come back to mainstream Assistant Director for the ever popular The English Patient.
The family tree is deeply ingrained in Italian film and TV making history and still going strong, Enzo is working on a new western with his favourite actor Franco Nero.
Now go to sleep.
