The Discovery Channel’s new summer ad campaign features a lot of old familiar faces, plus comedian Rob Riggle!

Riggle will host a new series for Discovery, Global Investigator, taking him all over the world to explore some of our greatest mysteries, myths and legends.

“I couldn’t be happier to be working with Discovery on another project. After taming sharks with Shaq in the Bahamas for Shark Week, I can’t wait to travel the world exploring some of our greatest mysteries,” Riggle said.

“Rob Riggle’s thirst for adventure is only matched by his extreme confidence in his own abilities. We’re thrilled to be working with him and can’t wait to show our viewers Rob’s unique take on some of the world’s biggest mysteries,” said Nancy Daniels, chief brand officer, Discovery & Factual.

Global Investigator is feeding into an untapped intersection of comedy and adventure,” said Will Packer, executive producer and CEO of Will Packer Media, which is producing the show. “I can’t think of anything more fun than hanging with Rob Riggle and traveling around the world.”
