A seventh compilation of some of the best acting scenes and/or performances of all time. I know there are many missing. It is just a glimpse. Also, it is a subjective list, I don't claim it to be objectively correct, if there's such a thing.
List of appearing actors/actresses in chronological order:
Robert De Niro - Taxi Driver
Michael Fassbender & Carey Mulligan - Shame
Bryan Cranston - Breaking Bad
Leslie Nielsen - The Naked Gun
Tilda Swinton & Ezra Miller - We Need To Talk About Kevin
Tom Hardy - The Revenant
Ulrich Noethen & Tom Schilling - Oh Boy
Robert De Niro & Al Pacino - Heat
