What's up with De Niro's eyes?

Rating: 7/10 (28 November 2019)

I enjoyed the movie and it was great seeing all these great actors together in a movie. Not a "Magnus Opus", like some people are calling it, but definitely worth seeing. It had a classic maffia movie vibe!
Just one thing; what was up with De Niro's eyes? His pupils seemed to be dilating at ghe wrong times. It was distracting.
