Christopher Walken

He counts reputable thespians like Johnny Depp and Kevin Spacey as his emulators/impressionists. He is defined by and "often imitated for his deadpan affect, sudden off-beat pauses and strange speech rhythm". (And what about those trademark facial tics?) His four-minute monologue in PULP FICTION still stands as one of the finest ever committed to film.
So who is he?
He is none other than Academy Award© winner Christopher Walken - one of my favorite actors working today.
