Here are three reasons why this film still hits differently in high definition:

The iconic five-tone musical sequence isn't just about sound; it’s a visual conversation. The vibrant colors of the light board against the night sky are stunningly saturated in a high-def remaster.

Douglas Trumbull’s legendary special effects are crisp and haunting. In HD, the contrast between the dark Indiana countryside and the blinding, colorful lights of the mothership creates a sense of scale that smaller screens used to lose.
