Written by Carlos Alazraqui (Reno 911!, Rocko's Modern Life, The Fairly OddParents) and Jill-Michele Melean (MadTV), Witness Infection is a dull-witted comedy that seeks to bind the mob movie with the zombie genre. Although it features an intriguing cast (including voice actors Maurice LaMarche and Tara Strong, amongst others), this braindead genre hybrid lacks the laughs, gore, and gags to truly do its concept justice.
