Altered is a 2006 American science fiction horror film directed by Eduardo Sánchez and written by Jamie Nash.

In its early stages, the film was titled Probed, and was intended as a comic homage to the work of Sam Raimi and Troma Entertainment.

The main character (Wyatt) has since distanced himself from his childhood friends and is shown to have decided to live with the past, albeit in apparent constant paranoia.

The story opens with the tracking and subsequent capture of a lone alien—the consequences of which Wyatt and the three friends soon become deeply involved in.
