'The Circle' Trailer: Tom Hanks Preaches Complete Technological Transparency to Emma Watson

"Knowing is good, but knowing everything is better."

Emma Watson and John Boyega are growing suspicious of their supervisor, Tom Hanks, in the first trailer for James Ponsoldt's The Circle.

The thriller, which Ponsoldt directed and adapted from Dave Eggers' best-selling book, follows a young employee, Mae (Watson), who is working her way up the corporate ladder at the world's largest tech company, where the company's founder (Hanks) encourages her to live with complete transparency.

"When we are our best selves, the possibilities are endless," says Hanks during a speech in the preview. "Without secrets, without the hoarding of knowledge and information, we can finally realize our potential."

EuropaCorp will release The Circle on April 28.
