In this terrific dolly-in shot of Edgar (Vincent D'Onofrio), the alien begins to take off his human skin. This shot was achieved both by on-set makeup effects supervised by Rick Baker and ILM's CG department in post-production.

Jeebs (Tony Shaloub) looks like a normal human being... ...until he's zapped by Tommy Lee Jones' weapon, and undergoes a series of incredible transformations. This incredible CG animation was handled by ILM's Tony Hudson and supervised by CG supervisor Carl Frederick.

A normal looking man discusses matters with Will Smith.

His eyes blink in a distinctively, un-humanlike manner in this wonderful, subtle digital effect.
