Apple TV's upcoming sci-fi thriller 'Liminal', based on J. Michael Straczynski's graphic novel 'Telepaths', has added Tom Pelphrey to its cast. The series is set in a world where a fraction of the population has superpowers after an electromagnetic disturbance. Pelphrey, who was recently seen in HBO's crime thriller 'Task', joins previously announced stars Yahya Abdul-Mateen II and Vanessa Kirby. 'Liminal' will be directed by Louis Leterrier and written by Justin Rhodes.

Why it matters

Apple TV has found success with high-concept sci-fi series like 'Silo', 'Pluribus', and 'Severance', and the addition of a talented actor like Tom Pelphrey to the cast of 'Liminal' further bolsters the project's potential. Pelphrey's recent acclaimed performance in 'Task' has raised his profile, and his involvement in 'Liminal' suggests Apple's continued commitment to attracting top-tier talent for its sci-fi offerings.

The details

Based on J. Michael Straczynski's graphic novel 'Telepaths', 'Liminal' is set in a world where a tenth of the Earth's population suddenly develops telepathic powers due to an electromagnetic disturbance. The story follows newly-telepathic Boston police officers as they confront a wrongly convicted prisoner who becomes a leader of other telepaths trying to escape a world that now sees them as targets. While the movie's plot may differ from the novel, the core premise of exploring a world where a subset of the population gains superpowers remains.

  • The graphic novel 'Telepaths' was originally published.
