Warner Bros. has released a teaser trailer for Johnny Depp sci-fier “Transcendence,” four months before its April 18 opening.

Paul Bettany and Rebecca Hall also star, with Wally Pfister helming and Alcon producing and financing in association with DMG Entertainment.

Depp portrays a researcher who is uploaded into a computer in the near future as the trailer indicates. “Once online, a sentient machine will overcome the limits of biology,” the voiceover notes.

The teaser does not appear to contain any actual footage.

Written by Jack Paglen, the screenplay was developed by Annie Marter and Straight Up Films, whose principals include Marisa Polvino, Kate Cohen and Regency Boies. Polvino, Marter and Cohen will produce along with David Valdes, Broderick Johnson and Andrew Kosove.
