15 Things You Somehow Missed In Oppenheimer

The vast majority of Oppenheimer was shot with a wide aperture, creating a razor-thin depth of field in which characters are isolated from their environments with pleasing, cinematic background blur.

And though Nolan often intentionally employs shifting focus throughout the film to depict Oppenheimer's frazzled mental state, there are also many scenes where focus is unintentionally soft.

Again, this was most easily spotted during the film's theatrical release - especially on an IMAX screen - but in countless dialogue scenes full of close-ups, actors' faces are slightly out of focus.

This is likely a result of Oppenheimer being shot on 65mm film with specialty lenses, because while focus-pullers can see crystal-clear playback while shooting digitally, they're resigned to using a lower-resolution video tap for film, where ascertaining clarity with a shallow depth of field becomes incredibly difficult for even the most skilled focus pullers.

And ultimately it appears that Nolan preferred not to discard a brilliant take from an actor for the sake of some buzzed focus which the vast majority of the audience would likely never notice, or at least not care.

But now you know it's there, you won't be able to un-see it.
