NEW SERIES

TWIST THE THROTTLE

Millions of people ride motorcycles and millions more fantasize about what it would be like to ride these cultural icons of speed, freedom and personal rebellion. HD Theater's new series TWIST THE THROTTLE takes audiences on a remarkable 36,000 mile journey across the globe to explore eight of the most famous sport motorcycle brands.

STUNT STARS

Traveling to the sets of popular television and movie productions, STUNT STARS examines how stunt professionals calculate and overcome the risks to bring the action to life on screen. From intentionally crashing cars, lighting themselves on fire or mastering a martial arts fight sequence, these unsung heroes and heroines of entertainment are highlighted in this action-packed series. Featuring Stunt Hall of Fame members like David Boushey, viewers gain a better appreciation for the craftsmanship, science and skill these professionals bring to work every day.

I COULD DO THAT!

This series profiles everyday people, who get their chance at the controls of machines they have always admired from afar and claimed they could master. Whether it is a giant crane operator, helicopter pilot or tug boat captain, each I COULD DO THAT! episode features three adventurous rookies and gives them the opportunity to take the reigns. However, first the participants go through a simulator-type experience and training from experts before getting their big break at the hands-on experience.

SUN-RIDE EARTH

The evolution of the runaway hit SUNRISE EARTH is SUN-RIDE EARTH, a first-person tour of scenic drives from majestic start to end. Just like SUNRISE EARTH, the series does not add music or narration. Instead, just the natural ambient sounds and hum of the engine complement the action as SUN-RIDE EARTH viewers experience the Acacia National Parkway in Maine at the height of fall foliage or cruise around the pristine Great Salt Lake surrounded by snowcapped mountains. Like every amazing journey, points of interest are highlighted along the way until the audience reaches the final destination, a spectacular vista showcased in exceptional high-definition.

MIGHTY SHIPS

Taking to the high seas, MIGHTY SHIPS explores the inner-workings of amazing vessels working the oceans, seas, lakes and rivers of the world. From the luxurious liner, the Queen Mary 2, to the current longest vessel in use, the Emma Maersk container ship, this series goes above and below deck to examine the mechanics and engineering that keep these boats ship-shape. Viewers are introduced to each ship's unique crew, including the Tyco Resolute's cable laying engineers, the veterinarians aboard the livestock ship M/V Becrux and the deckhands of the Canadian Coast Guard's icebreaker, Henry Larson.

THE WORLD'S MOST EXPENSIVE RIDES

This series scours the globe to profile the world's most expensive and extravagant cars, planes, boats and motorcycles � meaning anything that rolls, floats or flies and is spectacularly luxurious could be included.
