Netflix adds Canadian horror film 'Undertone' and Spanish thriller series 'El Silencio' to its catalogue

Netflix will stream the Canadian horror film *Undertone* beginning 11 July, a sound‑driven thriller directed by Ian Tuason that follows podcast host Evy Babic as she investigates paranormal audio recordings. The film received a generally positive reception, holding a 74 % rating on Rotten Tomatoes.

The platform also offers the Spanish psychological‑thriller miniseries *El Silencio*. The six‑episode series follows mute young man Sergio Ciscar, who killed his parents as a teen and is now observed by a psychiatric team to determine whether he poses a danger. The show explores the ambiguity between victim and perpetrator and has been highlighted as a compelling addition to Netflix’s Dutch library.

Both titles expand Netflix’s genre offerings for Dutch audiences, adding a horror‑film debut and a Spanish‑produced thriller to its streaming roster.
