Twin Films

https://en.wikipedia.org/wiki/Twin_films

""Twin films are films with the same, or very similar, plot produced or released at the same time by two different film studios."

I've noticed that some, certainly not all, the movies that Q references are "twin films". That is, the were the second (copy cats) so to speak.

Before The Matrix was Dark City

Before Iron Eagle was Top Gun

Before Big was Like Father, Like Son (87-88)

Just a thought. Mirror?
