Robert Englund has declined to appear in a planned remake of A Nightmare on Elm Street.

This changes nothing, The Robert Englund theory still stands.

The Robert Englund theory states that what all actors fear most, what is always haunting them in the back of their minds, is that at any point their careers might be derailed if Robert Englund decides that he wants to compete with them for a role. Robert Englund is still the greatest actor of all time, and because he wants no part in a bullshit likely vaporware remake of A Nightmare on Elm Street does nothing to change that. Actors know, Englund's still out there.
