Something has happened to PBS favorite “Charlie Rose.” The erudite conversations and sober intellectualism have been replaced by an absurd world where illogic, inane dialogues, and open hostility rule. The one-on-one interview between Charlie and his guest begins as usual but quickly goes awry, so much so that Charlie is warned that, somewhere, a man named “Steve” is “not happy.” But who is “Steve” and why is he angry? And why does the mere mention of his name stop Charlie cold? Using appropriated footage from a single episode of “Charlie Rose,” filmmaker Andrew Filippone Jr. creates something both disturbing and farcical in “‘Charlie Rose’ by Samuel Beckett.”
