When Julia (Maika Monroe) wakes up in a house controlled by an Artificial Intelligence system called Tau (Gary Oldman), she must figure out what its creator (Ed Skrein) wants with her and find a way to escape.
Having 99% of the film set in one location, scientist Alex’s home, gives it a claustrophobic feel as Julia begins to converse with Tau and the two of them form an unlikely connection as they learn from one another. The lighting has an influence on each scene as when Alex is home, everything is in shades of blue but when he leaves, and Julia and Tau are alone, the lighting is in shades of red. It contrasts the differences between Alex and Julia, Alex is logical and strives for control, while Julia is quick-thinking and strives for freedom.
Both Monroe and Skrein are great in their roles and when the two of them are caught in almost a battle of wits, the tension is at its peak. Julia is a memorable “final girl” who combines grim determination with hopefulness and a caring side.
Tau is a creepy horror-sci-fi hybrid that offers another take on the man verses AI dilemma we’ve seen in countless films over the years. However, Tau doesn’t really offer anything new in terms of commentary on AI’s and how as they become smarter, people may abuse them. There’s parallels made between the trauma Julia faced at the hands of her parents and the restrictions Alex puts on Tau, but it lacks any real depth. Still, with its 90-minute runtime, Tau is an engaging small-scale sci-fi flick. 3/5.
