Did You Know?


The first stock footage of the aircraft carrier is the USS Antietam, CV-36, the first US carrier with an angled deck. The operations clip is of the CV-34 USS Oriskany. They were both Essex-class carriers and most ships in this class received the SCB-125 upgrade, which installed the angled deck; however, the USS Oriskany was the LAST ship in this class to get the new deck. The take-off scene was from the deck of the USS Philippine Sea CV-47. The USS Oriskany (CV-34) was scuttled as an artificial reef in the Gulf of Mexico (May 2006). See more »

A good giant bug movie from Universal
25 June 2002 | by (Derby, England) – See all my reviews

The Deadly Mantis was made towards the end of Universal's 1950's cycle of monster/sci-fi movies. This one is one of the best.

A giant prehistoric mantis is awoken from a long sleep by atomic bomb testing in the North Pole. After going on the rampage in the frozen wastes and killing several people in the process, it heads first for Washington and then New York, where it is eventually gassed in Manhattan Tunnel.

The giant mantis in this movie looks quite impressive despite the low budget. The movie's cast is led by William Hopper (20 Million Miles to Earth). He and the others play good parts.

I found this movie quite enjoyable and is worth watching if you get the chance.

Rating: 4 stars out of 5.
