That kind of distortion is naturally common to most anamorphic lenses, but especially apparent in older glass. See: Soderbergh’s vintage anamorphic choices in N

That kind of distortion is naturally common to most anamorphic lenses, but especially apparent in older glass. See: Soderbergh’s vintage anamorphic choices in No Sudden Move. In the old days, they would mostly restrict anamorphics to locked off shots/specific compositions to minimize how visible these type of distortions can be.
