"You heard it here first, Space Spotters!"

The producers of the upcoming animated kids' TV special, Fireman Sam: Alien Alert, have given viewers a first glimpse of the production in a short video trailer.

Due on TV in May 2017, the special one hour feature sees the little village of Pontypandy hit by a raft of UFO sightings. Fireman Sam, everyone's favourite hero next door, is determined to get to the bottom of the mysterious events. David Tennant joins regular cast members Steve Kynman and Tegwen Tucker, voicing the villain, an alien-hunting TV presenter called Buck Douglas whose arrival in town stirs up excitement as residents anticipate featuring on his 'Alien Quest' show.

“Alien Alert is an action-packed Fireman Sam adventure for pre-schoolers, and we’re delighted to have the talented David Tennant on board as the voice of Buck," said Christopher Keenan, senior vice president, global content and executive producer at Mattel Creations.

"The special stays true to core Fireman Sam values - bravery, loyalty, heroism, community and teamwork - but takes us to new levels of excitement with a sci-fi slant that includes new characters, rescue vehicles, locations, and plot twists. Producing Alien Alert has been an incredible joy and we're confident that our young audience will be captivated by our most dramatic Fireman Sam story yet.”

Fireman Sam: Alien Alert is produced by HIT Entertainment and distributed worldwide by DHX Media.
