Be Right Back vs. Ex Machina parallels

⚠️ SPOILER WARNING - S2E01⚠️

I noticed that Ash’s actor (Domhnall Gleeson) played opposite roles in black mirror’s BRB, and the sci-fi movie Ex-Machina.

In BRB, he played a robot that imitated human behavior.

In Ex-Machina, he played a human who tried to understand whether a robot was imitating human behavior or acted genuinely.

Is there anything this man can’t do??
