Sony Imageworks have released a new featurette for The Amazing Spider-Man 2, offering up a look at how Electro’s powers were brought to life on the big screen.

In the movie, Max Dillon gains his powers through contact with electric eels, and the team who worked on the sequel reveal here that those creatures played a role in how they decided to portray the villain’s powers.

In The Amazing Spider-Man™ 2, for Peter Parker (Andrew Garfield), life is busy – between taking out the bad guys as Spider-Man and spending time with the person he loves, Gwen (Emma Stone), high school graduation can’t come quickly enough. Peter hasn’t forgotten about the promise he made to Gwen’s father to protect her by staying away – but that’s a promise he just can’t keep. Things will change for Peter when a new villain, Electro (Jamie Foxx), emerges, an old friend, Harry Osborn (Dane DeHaan), returns, and Peter uncovers new clues about his past.

Starring Andrew Garfield, Emma Stone, Jamie Foxx, Dane DeHaan, Chris Cooper and Paul Giamatti, The Amazing Spider-Man 2 is out now!
