Did You Know?


In this film, Axel Milberg is playing Jupiter's father. In 2017, Milberg became the narrator of the popular German audio series "Die drei Fragezeichen", which is based on the The Three Investigator books. See more »


At the beginning of the movie the Rolls Royce is seen driving on the right side of the road. At the end of the movie, as the boys return from their trip, the Rolls drives on the left side, which is wrong for California, but correct for South Africa, where the movie was filmed. See more »


Jupiter Jones: You know, maybe you could help us. There was a girl we met last night. Red hair, pale eyes.
Bob Andrews: Real goofy. Off the wall. Believes in all this, uh, loony hocus pocus stuff. Just... absolutely nuts. Uh, her name's Caroline. Do you know her?
Sheriff Hanson: That's my daughter.

User Reviews

Recommended for "age 10 to 13 and haven't read the book". Adults stay away.
2 September 2010 | by kindredparadoxSee all my reviews

Reading earlier reviews I deduce that "T3I and the Secret of Terror Castle" does not meet their expectation. We easily understood that because this movie is really targeted to adolescent and below. If I was that age I would probably truly enjoy the movie but only if I haven't read the book yet. Kids would easily enjoy this movie because it's cool enough, such as the castle.

I was afraid to watch this movie for the reason that it would tarnish my good memory of Three Investigators and it prove to be true. When I was reading the book I always feel fascinated, the location, the characters it seems just magical. Watching the movie, it seems that it is a different world from the one in the book.

As I said that it would entertain many kids which just watching it now and never had reading the book before, we adults that enticed to watch it in which we demand something else than those kids will be disappointed. We adults hope to see interesting and eccentric characters and dialogs, that cool accents from Jupiter Jones, more peculiar music soundtrack, and more magical-feel but normal-looking towns would not get what we want. We won't even entertained by the case which is the one most interesting thing why we want to read the next novel.

For young men don't miss this one for it is really rare this kind of movie around: Kids Detective that investigate peculiar case without an element of Action in which nowadays detective movie would always combined.
