Ahead of this month’s release of Jason Bourne, Matt Damon reprises his role in a prank video with Omaze to raise money for Water.org.

Damon set up a simulation in Los Angeles, awarding unsuspecting individuals the chance to feel like they’re in a spy movie, much like the Bourne films. The unsuspecting bystanders found themselves involved in spy games with Jason Bourne and company, and in the end — if they followed his directions — won an awesome prize.

Jason Bourne hits theaters July 29. See the movie trailer below.
