The Edinburgh International Film Festival is doing one of its retrospectives on the live action comic book adaptation. It is focusing upon the 1960s and 1970s. Diabolik and Baba Yaga will be shown, though unfortunately a Tarkan or Killing seems unlikely.
In relation to this I was amused to discover Erotik, a hardcore fumetti Diabolik rip-off cum (groan!) parody. Or Not Diabolik XXX, a Porn Parody, avant la lettre.
