QUICK ANSWER & VERDICT

Oppenheimer uses color ('Fission') for J. Robert Oppenheimer's subjective memory and IMAX black-and-white ('Fusion') for Lewis Strauss' objective political scheming, uniting both threads at the final Einstein lakeside confession.

Spoiler-Free Summary

Framed as two colliding hearings rather than a standard cradle-to-grave biopic, Oppenheimer contrasts scientific obsession against bureaucratic betrayal.
