Andre Agassi voices #VegasStrong short film

In the wake of the greatest human toll in a mass shooting in the United States, the Las Vegas Convention and Visitors Authority released a brief film. Vegas resident Andre Agassi voices the minute-plus piece as the glowing Vegas Strip slowly emerges from the distance.

The clip is straightforward and somber as it should be.

"Strength isn't anger. Strength isn't vengeful. Strength isn't rage," Agassi says. "Strength is unity. Strength is valet parkers who become medics. Mothers who become emergency responders. Sisters who shield brothers because they love them with a love that has no bounds. Strength is first responders who tirelessly carry visitors and locals alike to safety until sunrise. It's our medics and surgeons, all of them, who come running to the calls of all of those in need."

"Strength isn't evil, or misguided," the tennis great continues. "Strength is the voice of community and love in the face of the unspeakable. Strength is when we all pull together, and rise up – all of us in every corner of this world. Strength is what we all are today, and strength is our promise for tomorrow."

The October 1 shootings that precipitated the clip were the work of a lone gunman, who claimed 58 human lives and injured more than 500 other people during Jason Aldean's outdoor performance at a country music festival near the Mandalay Bay Resort and Casino.

Since that tragedy, the #VegasStrong hashtag has also been used by many local and national organizations and public figures.

Another decorated tennis icon, Steffi Graf (Agassi's wife) published a brief Facebook post about the massacre.

As Agassi himself says, the city of Las Vegas rebuilds on the strength of the promise for tomorrow.
