Watch: Isaiah Mustafa in cologne ad making-of

It is fair to say that the Old Spice ads starring former American football player Isaiah Mustafa, now known as "the Old Spice guy," are some of today's biggest viral successes as well as some of the most accomplished productions in advertising, but how does their mindblowing change of scenery actually work?

Old Spice has released a making-of video that shows fans how Mustafa and his team use a combination of set-building and technology to achieve the rapid succession of sites and settings, while the Old Spice guy remains seemingly unfazed by it all, happily holding props in front of the camera.

Mustafa, who got millions of views for each installment (as well as plenty of celebrity video responses), will star in the Hollywood movie Horrible Bosses, set for release later this year.
