Robert Pattinson has surprised fans by revealing his transformation into Chris Hansen for the upcoming A24 thriller "Primetime," with the film's first trailer released on Thursday. Directed by Lance Oppenheim, the film follows Hansen, best known for hosting Dateline NBC's "To Catch a Predator", as he attempts to make television history in the 2000s using undercover sting operations to expose would-be sexual predators.

The trailer has drawn strong reactions online, with viewers describing Pattinson's uncanny physical likeness to Hansen as "unsettling". "To Catch a Predator" was a widely watched and controversial series during its original run, and the new film appears set to explore the making and impact of the show through a dramatised lens.
