Oppenheimer's last scene has already become a huge talking point like Christopher Nolan's Inception

As Oppenheimer blasts its way into cinemas, the film’s ending has already become a huge talking point for fans.

It’s not unsurprising given that the movie is directed by Christopher Nolan, the man behind the incredibly complicated Inception.

Despite being based on the life of scientist J. Robert Oppenheimer, the biopic's ending shares a striking similarity with Inception and has become a major topic of conversation for viewers.

** Warning - spoilers ahead **

If you still haven’t watched Inception, here’s a quick rundown - although you really should have considering the film is over a decade old.

The final scene sees dream architect and criminal Dom Cobb (Leonardo DiCaprio) evading the authorities and finally reuniting with his children.

Sadly though, it's unclear whether this is also imagined with the iconic totem toppling off-screen.

Film buffs have been debating the moment since its release back in 2010, with some even reaching out to Nolan about the thought-provoking ending.

Similarly, Oppenheimer has an equally depressing note with the titular scientist (Cillian Murphy) looking up at a giant nuclear missile with the camera slowly revealing rows upon rows of the weapons.

As they launched into the sky, viewers then see the Earth from space as a nuclear war consumes the planet.

Though unreal, it signifies the frightening new reality after Oppenheimer created the A-bomb and has caused audiences to reflect on the problem of having such a weapon.

Those who’ve seen the movie have been insanely impressed with the ending, taking to social media to discuss the film.

One wrote: “That last scene and dialogue gave me chills. The film shows all the drama, politics and guilt of Oppenheimer really well.”

Another argued that the final scene ‘redeemed’ the entire film, writing: “Nolan redeemed his movie with the last scene, and the last scene alone (starting with that final chat with Einstein).”

They added: “Lots to think about for Los Alamos residents who take Oppie for a hero.”

Meanwhile, a third wrote: “This movie had so much hyped built around it and it lives up for it and more… 3 hours of pure brilliance especially the last scene.”

A final viewer penned: "Oppenheimer was insanely powerful stuff. That last scene omgggg."

Oppenheimer is in cinemas now.
