Thunderbird 6

Like the "Thunderbirds" TV series and the film "Thunderbirds Are Go", this movie covers the adventures of the Tracy family of super-secret rescue agents. But although the effects are as good, this time plot defects injure the story.

The characters pretty much ignore their "secret" status when they openly sign on as passengers for an experimental antigravity ship, which turns into a Titanic-style disaster when a crew of saboteurs take over. They did cute things with the "Supermarionation" marionets (like skiing scenes). But the plot holes finally drag down the film.

Even Anderson's generally-excellent special effects suffer; in place of elaborately staged scenes with a model, the film's rescue craft (a biplane) is often shot as a radio-controlled model plane shot in reality, buzzing a real castle instead of Lady Penelope's soundstage set. It's not convincing. Republic's movie serials were able to mix real-world buildings with props well; Century 21 Productions didn't do it here.
