Next month is set to be quite the explosive one when it comes to blockbusters, and fans of Christopher Nolan are getting especially hyped for his latest film Oppenheimer, which hits theaters on July 21st.

Nolan himself shares that notion, that what will undoubtedly be the crowning achievement of his filmmaking career (so far) may very well be too much for even his biggest fans.
