Boy, does this show its age!* But, you know what, I really enjoyed it.
'Eight Legged Freaks', eat your heart out! I seem to have found a new go-to Spider Rampage Flick™. To be serious, 'Tarantula' achieves what it intends to - it is relatively creepy in parts.
The special effects, as alluded to, have aged averagely, but there are still some excellent shots in there. When the spider is in a wide shot it looks very neat, the issues tend to arise when the creature is at the forefront of the shot - which turns into a sharp black-and-white shadow clash. Speaking of the b/w, it is a very dark film visually; especially for the night scenes. The make-up effects look great, either way though.
Leo G. Carroll, John Agar and Mara Corday are all good fun in their respective roles, they work well together which is obviously important. Corday oddly reminds me a lot of modern day actress Madelyn Cline - I'm not entirely sure why, I think it's Corday's facial expressions/mannerisms.
Clint Eastwood has another small - though, quite the opposite in plot terms - role, this time towards the conclusion. He has a few lines of dialogue, but it's not a role of his that'll live long in the memory.
To think, Universal made 7 'Francis' films but produced just one of these. Unfortunate. I'd be up for a remake.
'* = I'm sure, and I am led to believe, it looked great for the time.
