Batman V Superman: 15 Theories That Were Utter Bull
7. Benedict Cumberbatch Is Playing Brainiac
The Rumour: Because a playful Benedict Cumberbatch refused to deny it, his legion of fans became obsessed with the notion that he might be playing a secret villain, most likely Brainiac, in the movie.
How Much We Believed It: Even with Cumberbatch's ruse, this one was hard to buy into, especially once the actor was cast as Doctor Strange in the Marvel Cinematic Universe. Plus, isn't Doomsday enough for one movie? 1/10
The Truth: This one was, as expected, total bulls***, as Brainiac isn't even remotely hinted at throughout the film.
