"Ashley Judd gives the kind of fearless, raw performance that you only see a few times a year."
— Brian Tallerico, UGO
"William Friedkin's latest film, Bug, begins as an ominous rumble of unease, and builds to a shriek."
— Roger Ebert, Chicago Sun-Times
"Bug goes exactly where it needs to go -- to a place most filmmakers don't dare go -- and gets there brilliantly."
— Mick LaSalle, San Francisco Chronicle
"A tour de force of acting and directing in this spellbinding exercise from director William Friedkin, back in his old form."
— Frank Lovece, Film Journal International
"It starts off like a horror film, or like a modern-day Tennessee Williams piece and then transmutes into ... something very different indeed."
— Peter Bradshaw, Guardian
"As in The Exorcist, Friedkin establishes a tone of hard-edged, almost documentary-style realism before ratcheting up the horror to nearly unbearable levels."
— Nathan Shafer, AV Club
"Bug, directed by William Friedkin from Tracy Letts's play, has the feverish compression of live theater and the moody expansiveness of film. The mix is insanely powerful."
— David Edelstein, New York Magazine/Vulture
