Scorcese's "The Irishman" is a tour de force of filmmaking, storytelling and performances by DeNiro, Pesci, and Pacino. An epic true tale of organized crime and Jimmy Hoffa. I highly recommend you find 3.5 hours in your life to watch it.

Scorsese prides himself on getting setting details 100% accurate in his period piece movies. In The Irishman however, there is a major goof in an airport/airplane scene that takes place in 1975. Now remember Scorcese directed "The Aviator" so he knows something about airplanes and aviation. In this 1975 scene, DeNiro enters a Cessna 421 Golden Eagle. As he sits down before take-off we clearly see the instrument panel which contains 2 glass panels(they look like Garmins) within a bunch of steam gauges which of course did not exist in 1975. Furthermore, the tail number is clearly shown as N212RV. A quick lookup states this airplane was manufactured in 1979, a full 4 years after the year of this scene.

Now I know this is just fun for us GA guys(male and female) to see, mock and point out but somebody on the crew should have caught this anachronism.
