Babes, executive suites, quadrilingual fluency, and riches beyond your wildest dreams: In the new thriller Limitless, out this Friday, Eddie Morra (played by Bradley Cooper) lands it all thanks to a stash of the make-believe drug NZT. Or is it make-believe? Global entrepreneur Sir Richard Branson — whose new production company, Virgin Produced, just happens to have helped shepherd Limitless into theaters — appears as spokesperson in a new “ad” for NZT, asserting the drug is his own secret weapon. Check it out exclusively below:

When EW asked Sir Branson if he’d fear people might actually believe the ad, he said, “What, are you saying you don’t believe the ad?” Branson assures us he’s experienced zero negative side effects, but added, “My time machine is always in the repair shop from overuse.”
