"Inside is a captivating thematic feast anchored by the ever-masterful Willem Dafoe."
— Charlotte Simmons, We Got This Covered
"Inside is set up as a psychological thriller/escape movie, but evolves into something rather more intriguing: a philosophical interrogation of the value of art to a dying man."
— Wendy Ide, Screen Daily
"It’s always Dafoe — perhaps channeling the audacious immersion of his roots in Wooster Group theater — who mesmerizingly portrays this “Inside” job as if his life and art counted on it."
— Robert Abele, TheWrap
"A novel take on the heist film, Inside fosters a surreal, unnerving atmosphere and makes voyeurs of its audience – like spectators in a gallery, murmuring about the meaning of a dead man’s art."
— Hannah Strong, Little White Lies
"Still, the greatest asset of the picture is Dafoe’s finesse in a part that’s both physically demanding and fiendishly fun to witness. It’s like someone dropped him in the middle of an antique shop with a baseball bat and said, “Go to town!” And that he does."
— Tomris Laffly, The A.V. Club
"Everything is glued together by another Dafoe performance that proves he’s one of the greatest actors of all time, especially when given enough room to tap into the lunacy of his characters. In short, Katsoupis managed to craft a crowd pleaser that still has something interesting to say."
— Marco Vito Oddo, Collider
