Tarantula (film)
Tarantula (1955) is an American science-fiction monster film directed by Jack Arnold. It stars John Agar, Mara Corday, and Leo G. Carroll. The story centers on a scientist who develops a miracle nutrient to feed a growing world population. In an unperfected form, the nutrient causes extraordinary growth, and when a tarantula test subject escapes, it begins to grow to enormous size, creating a deadly threat.
Plot in simple terms:
- In Desert Rock, Arizona, Dr. Gerald Deemer works on a radioactive super-nutrient to feed humanity. His assistant, Paul Lund, sabotages a lab experiment, causing a fire. The tarantula in the lab escapes and keeps growing, while Lund dies.
- Hastings, a doctor, and Steve Clayton arrive in town to learn more. Hastings suspects something is wrong with Deemer’s work, and Clayton helps investigate.
- Deemer becomes physically deformed from the nutrient’s effects, and he reveals that Lund and another scientist tested the substance on themselves despite his warnings.
- The team discovers that the mysterious white liquid found at animal attack sites is actually tarantula venom. The giant tarantula attacks the mansion and the town.
- A dramatic chase ends when an Air Force fighter squadron drops napalm on the monster, incinerating it. An uncredited Clint Eastwood appears as the jet squadron leader.
Production notes in simple terms:
- The film was shot mostly in California, with desert scenes filmed around Apple Valley and Lucerne Valley.
- Special effects combined real animals (including a live tarantula) for the giant spider scenes with miniature models for close-ups.
- The film aimed to tap into audiences’ fear of spiders, using practical effects rather than sci-fi gadgets.
- The poster’s spider image is not from any scene in the movie.
Reception and legacy:
- Tarantula was a notable 1950s creature feature, offering fast pacing and impressive effects for its time.
- It was successful at the box office, earning about $1.1 million in US and Canada rentals.
- Critics like Leonard Maltin gave it solid praise for being a strong entry in its subgenre.
- The film has a lasting place in sci-fi history for its practical effects and desert atmosphere, and it’s sometimes discussed alongside other giant-insect films of the era.
- It has appeared on home video since 2006 and has been released in various Blu-ray formats in later years.
Interesting tidbits:
- The film’s theme centers on a well-intentioned scientist whose work spirals out of control, rather than a villainous mad scientist.
- Tarantula’s giant creatures and dramatic destruction are often compared to other 1950s monster films, highlighting the era’s imaginative use of effects.
