This video is basically the endpoint of the joke pretty much everyone was making after the first trailer for Oblivion came out. Namely, a lot of people observed that the plot of Oblivion, which sees a lonely Tom Cruise patrolling an Earth devoid of human life in the wake of a catastrophe, seems quite similar to that of WALL-E, which saw a lonely robot patrolling an Earth devoid of human life in the wake of a catastrophe. And then both their existences are upended by the arrival of a mysterious female… and it turns out that Earth isn’t so devoid of life after all, etc etc. You get the idea.
Now, YouTube user Giant Mimosas has combined the audio from the Oblivion trailer with footage from WALL-E, to comedic effect. It’s a great little work of editing, as they’re able to match up the beats from the former with appropriate visuals from the latter.
It’s fun. Have a watch:
