At the moment, I’m partial to this one.
Me too. My favorite depiction on film would be Randall Flagg (who is essentially Satan) as portrayed by Jamey Sheridan in The Stand TV miniseries. Stephen King was fond of saying how he imagined Satan as a “funny, charming guy” and that’s exactly the performance Sheridan delivered. Another favorite (though not as funny) would be Satan masquerading as a teenage guardian angel in The Last Temptation of Christ – it’s always who you least suspect, isn’t it?
