Mimic 3: Sentinel is a 2003 science fiction horror film, directed by JT Petty, with a script inspired by a short story of the same name by Donald A. Wollheim. The movie was a direct-to-DVD sequel to Mimic (1997) and Mimic 2 (2001).Mimic 3: Sentinel stars horror film veteran Lance Henriksen and takes a departure from the tone of the first two films, as it has a feel similar to Alfred Hitchcock's Rear Window rather than the action/horror tone of its predecessors.
