Idris Elba is taking an adventurous career detour to topline a docu-series about racing for Discovery Communications networks.

The actor known for his on-screen intensity in the BBC drama “Luther” and HBO’s “The Wire” will immerse himself in racing on land, sea and in the air for a series designed to shed light on the mechanics of speed. The four-episode skein is slated to air in mid-2015 on Discovery in the U.S. and across international markets.

The series with the working title “The Idris Elba Project” is a production of Elba’s Green Door Pictures and Shine North. It’s a commission of Discovery Networks U.K.

Elba said the series will depict his training with top engineers and racing experts as he prepares for various racing challenges.

“I’ll meet extraordinary individuals, spectacular machines and hear amazing stories of how far people go to satisfy their love of speed,” Elba said in a statement. “The extreme challenges will take me right out of my comfort zone as I compete against the best on land, water and in the air.”

The project stems from the production pact that Green Door and Shine North set earlier this year. Elba, Discovery’s Victoria Noble and Shine North’s Rick Murray are exec producers.

Elba’s upcoming feature projects include Jon Favreau’s “The Jungle Book” and co-starring with Sean Penn and Javier Bardem in helmer Pierre Morel’s “The Gunman.”
