I've decided, for convenience, to see the Oppenheimer movie on a "small" screen at my neighborhood theater on Tuesday afternoon for $6.50. I will then decide if I want to try for the IMAX 70mm at the Dallas Cinemark, if the run is extended, for the chance of getting other than 1st three rows seating...
‘Oppenheimer’ Cast and Historical Guide: The Real People Behind the First Atomic Bomb
https://variety.com/lists/oppenheimer-cast-guide-manhattan-project/
The one thing you need to know about Christopher Nolan’s “Oppenheimer” is that it moves incredibly fast and covers a lot of ground. For most of its three-hour runtime, the atomic bomb epic can feel as if you’re reading a dense biography about J. Robert Oppenheimer at three times the normal speed. With so many scientist characters orbiting Oppenheimer at light speed, you’d be forgiven for feeling a little lost at times.
To help watch “Oppenheimer” with a bit more clarity, it’s important to know the movie takes place
during three time periods. One timeline is set in 1954 as the U.S. Atomic Energy Commission (AEC) holds a security hearing to investigate whether or not Oppenheimer (Cillian Murphy) is a Soviet spy. The hearing prompts the film to flash back to the events of Oppenheimer’s life, from his university days to his role in creating the atomic bomb. These portions of the film, shot in color, make up the bulk of “Oppenheimer’s” three-hour runtime.
A third storyline is shot in black and white and takes place in 1959 as Lewis Strauss (Robert Downey Jr.), the former chairman of the U.S. Atomic Energy Commission, is seeking to become U.S. Secretary of Commerce under President Dwight D. Eisenhower. Strauss finds himself at the center of his own U.S. Senate confirmation hearing, which threatens to expose his involvement in the events of the 1954 timeline.
