Corrected entry: At end of the film Caleb tries to access the shutdown through the computer but the power cut stops him. Only Ava can manually trigger power-cuts by placing her hand on her wall charger and she was gone - she has no ability to do delayed or timed cuts.

Ex Machina (2015)
1 corrected entry
Directed by: Alex Garland
Starring: Oscar Isaac, Alicia Vikander, Domhnall Gleeson, Sonoya Mizuno
Factual error: When Caleb is entering the estate in the helicopter, the pilot mentions they had been flying over the estate for the past two hours, indicating that it was two hours to Nathan's house plus any time elapsed after that conversation. Calculate another two hours minimum back to the airport. The Eurocopter EC 130 pictured in the film has a maximum range of about four hours max. The helicopter quite possibly could've crashed before reaching the airport to refuel. (00:02:01)
Trivia: Adjusted for inflation, Ex Machina is the lowest-budgeted winner of the Academy Award for Best Visual Effects in history. In 2019, its budget comes to around $16 million, with the closest equivalent being the $41 million of Cocoon (1985).
Question: SPOILER If, by the end of the movie, the facility was reprogrammed to have all doors unlocked on a power failure - and there was a sudden power failure when Domhnall inserted the card into the computer terminal... Why did he remain locked within? Shouldn't he be set free by the programming change he freed Ava with?
Chosen answer: He inserted his own card in Nathans computer. Also, there was no mention of a power failure, only a red glow. This would be a different event than he's programmed the system for.
Answer: The "Red glow" was the emergency lights that had come on every other time the power went out. And the final power outage was orchestrated by previous arrangement by the robot and Caleb.

Correction: Ava is only shown twice to use the wallpad to trigger a power cut. Multiple power cuts occur while she is standing or sitting in the middle of the room, so she can trigger them remotely, timed, or when certain triggers initiate them, such as accessing the computer.
