The first 'Clifford The Big Red Dog' trailer has been unleashed to the masses - and it's been getting a lot of attention online.

The story, based on the children's book series by author Norman Bridwell, sees a young girl discover a magical small red puppy, who grows to gargantuan size overnight.

While her single mom (Sienna Guillory) is away for business, Emily and her fun but impulsive uncle Casey (Jack Whitehall) set out on an adventure that will keep you on the edge-of-your-seat as our heroes take a bite out of the Big Apple.
