I think he was referencing this scene from Contact:
I like it, apart from Jodie Foster's acting towards the end. It has an amazing opening scene and how they filmed her as a child running towards the bathroom mirror was pretty clever. Most of the movie is pretty entertaining with its twists and turns trying to decipher the signal.
Watching it as a kid, I was also fascinated by the brief look at the weird alien structure (turned out to be their radio array) and the alien planet, when the camera pans down from the quadruple star system to the surface and you see how their cities are lit up at night.
