The Irishman would have to be a cinema classic to make up for De Niro's last decade, but then again his highest-ever grossing movie was that Fokkers one so what do I know.
I wonder if the de-aging is an attempt to confuse audiences that they're watching some undiscovered work from his prime before he started working with Luc Besson? God that was an upsetting 2 hours.
Genuine question, his last three films have been Hugo, Wolf of Wall Street and Silence - about as on track as you can get, no?
