The 50th anniversary Thunderbirds episode "Introducing Thunderbirds" as you've never seen it before, with extended moments from the cutting room floor. In 2015, the team from Century 21 Films adapted the 1965 Thunderbirds mini-album "Introducing Thunderbirds" or the screen as part of the series' fiftieth anniversary celebrations. As part of the adaptation process, certain scenes were edited for timing and pacing reasons. In this new version, we present for the first time the extended cut with some of these scenes restored. "Introducing Thunderbirds" takes place before "Trapped in the Sky" and tells the story of Lady Penelope's induction into the International Rescue organisation by Jeff Tracy. Parker is along for the ride, though this beautiful island getaway isn't quite as relaxing for him.
