'Oppenheimer' doesn't get Einstein's relationship with the Los Alamos director quite right. Here's what they really thought of each other.

• Albert Einstein plays a significant role in the Christopher Nolan film, "Oppenheimer."
• In reality, Einstein and J. Robert Oppenheimer knew each other but weren't friends until much later.
• The real Einstein wouldn't have helped Oppenheimer with top-secret calculations about the atomic bomb.

For someone who wasn't involved in the race to develop the first atomic bomb, Albert Einstein plays a surprisingly significant role in the Christopher Nolan film "Oppenheimer."
